The new netlink API for reading SFP data requires a new op to be implemented. The idea of the new netlink SFP code is that userspace is responsible to parsing the EEPROM data and requesting pages, rather than have the kernel decide what pages are interesting and returning them. This allows greater flexibility for newer formats. Currently the generic SFP code only supports simple SFPs. Allow i2c address 0x50 and 0x51 to be accessed with page and bank must always be 0. This interface will later be extended when for example QSFP support is added. Signed-off-by:

In case netlink get_module_eeprom_by_page() callback is not implemented by the driver, try to call old get_module_info() and get_module_eeprom() pair. Recalculate parameters to get_module_eeprom() offset and len using page number and their sizes. Return error if this can't be done. Signed-off-by:

There are two ways to retrieve information from SFP EEPROMs. Many devices make use of the common code, and assign the sfp_bus pointer in the netdev to point to the bus holding the SFP device. Some MAC drivers directly implement ops in there ethool structure. Export within net/ethtool the two helpers used to call these methods, so that they can also be used in the new netlink code.

Define get_module_eeprom_by_page() ethtool callback and implement netlink infrastructure. get_module_eeprom_by_page() allows network drivers to dump a part of module's EEPROM specified by page and bank numbers along with offset and length. It is effectively a netlink replacement for get_module_info() and get_module_eeprom() pair, which is needed due to emergence of complex non-linear EEPROM layouts. Signed-off-by:

Alex Elder says: ==================== net: ipa: a few small fixes This series implements some minor bug fixes or improvements. The first patch removes an apparently unnecessary restriction, which results in an error on a 32-bit ARM build. The second makes a definition used for SDM845 match what is used in the downstream code. The third just ensures two netdev pointers are only non-null when valid. The fourth simplifies a little code, knowing that a called function never returns an error. The fifth and sixth just remove some empty/place holder functions. And the last patch fixes a comment, makes a function private, and removes an unnecessary double-negation of a Boolean variable. This patch produces a warning from checkpatch, indicating that a pair of parentheses is unnecessary. I agree with that advice, but it conflicts with a suggestion from the compiler. I left the "problem" in place to avoid the compiler warning. ==================== Link: https://lore.kernel.org/r/20210409180722.1176868-1-elder@linaro.orgSigned-off-by:

Some time ago changes were made to stop referring to clearing the hardware pipeline as a "tag process." Fix a comment to use the newer terminology. Get rid of a pointless double-negation of the Boolean toward_ipa flag in ipa_endpoint_config(). make ipa_endpoint_exit_one() private; it's only referenced inside "ipa_endpoint.c". Signed-off-by:

There are place holder functions in the GSI code that do nothing. Remove these, knowing we can add something back in their place if they're really needed someday. Some of these are inverse functions (such as teardown to match setup). Explicitly comment that there is no inverse in these cases. Signed-off-by:

There are place holder functions in the IPA code that do nothing. For the most part these are inverse functions, for example, once the routing or filter tables are set up there is no need to perform any matching teardown activity at shutdown, or in the case of an error. These can be safely removed, resulting in some code simplification. Add comments in these spots making it explicit that there is no inverse. Signed-off-by:

In ipa_modem_stop(), if the modem netdev pointer is non-null we call ipa_stop(). We check for an error and if one is returned we handle it. But ipa_stop() never returns an error, so this extra handling is unnecessary. Simplify the code in ipa_modem_stop() based on the knowledge no error handling is needed at this spot. Signed-off-by:

In ipa_modem_start(), we set endpoint netdev pointers before the network device is registered. If registration fails, we don't undo those assignments. Instead, wait to assign the netdev pointer until after registration succeeds. Set these endpoint netdev pointers to NULL in ipa_modem_stop() before unregistering the network device. Signed-off-by:

On IPA v3.5.1, the sequencer type for the modem TX endpoint does not define the replication portion in the same way the downstream code does. This difference doesn't affect the behavior of the upstream code, but I'd prefer the two code bases use the same configuration value here. Signed-off-by:

I no longer know why a validation check ensured the size of an entry passed to gsi_trans_pool_init() was restricted to be a multiple of 8. For 32-bit builds, this condition doesn't always hold, and for DMA pools, the size is rounded up to a power of 2 anyway. Remove this restriction. Signed-off-by:

Even if the current mapping is correct for the 1 CPU and 2 CPU cases (currently enetc is included in SoCs with up to 2 CPUs only), better use a generic rule for the mapping to cover all possible cases. The number of CPUs is the same as the number of interrupt vectors: Per device Tx rings - device_tx_ring[idx], where idx = 0..n_rings_total-1 Per interrupt vector Tx rings - int_vector[i].ring[j], where i = 0..n_int_vects-1 j = 0..n_rings_per_v-1 Mapping rule - n_rings_per_v = n_rings_total / n_int_vects for i = 0..n_int_vects - 1: for j = 0..n_rings_per_v - 1: idx = n_int_vects * j + i int_vector[i].ring[j] <- device_tx_ring[idx] Signed-off-by:

The blamed commit introduced a bit in the TX software buffer descriptor structure for determining whether a BD is final or not; we rearm the TX interrupt vector for every frame (hence final BD) transmitted. But there is a problem with the patch: it replaced a condition whose expression is a bool which was evaluated at the beginning of the "while" loop with a bool expression that is evaluated on the spot: tx_swbd->is_eof. The problem with the latter expression is that the tx_swbd has already been incremented at that stage, so the tx_swbd->is_eof check is in fact with the _next_ software BD. Which is _not_ final. The effect is that the CPU is in 100% load with ksoftirqd because it does not acknowledge the TX interrupt, so the handler keeps getting called again and again. The fix is to restore the code structure, and keep the local bool is_eof variable, just to assign it the tx_swbd->is_eof value instead of !!tx_swbd->skb. Fixes: d504498d ("net: enetc: add a dedicated is_eof bit in the TX software BD") Reported-by:

napi_disable() is subject to an hangup, when the threaded mode is enabled and the napi is under heavy traffic. If the relevant napi has been scheduled and the napi_disable() kicks in before the next napi_threaded_wait() completes - so that the latter quits due to the napi_disable_pending() condition, the existing code leaves the NAPI_STATE_SCHED bit set and the napi_disable() loop waiting for such bit will hang. This patch addresses the issue by dropping the NAPI_STATE_DISABLE bit test in napi_thread_wait(). The later napi_threaded_poll() iteration will take care of clearing the NAPI_STATE_SCHED. This also addresses a related problem reported by Jakub: before this patch a napi_disable()/napi_enable() pair killed the napi thread, effectively disabling the threaded mode. On the patched kernel napi_disable() simply stops scheduling the relevant thread. v1 -> v2: - let the main napi_thread_poll() loop clear the SCHED bit Reported-by:

The ethernet frame length is calculated incorrectly. Depending on the value of RX_HEAD_PADDING, this may result in ethernet frames that are too short (cut off at the end), or too long (garbage added to the end). Fix by calculating the ethernet frame length correctly. For added clarity, use the ETH_FCS_LEN constant in the calculation. Many thanks to Heiner Kallweit for suggesting this solution. Suggested-by:

[0] nr-gpios is referenced in Documentation/devicetree/bindings/gpio: - gpio-adnp.txt - gpio-xgene-sb.txt - gpio-xlp.txt - snps,dw-apb-gpio.yaml [1] Link: https://github.com/devicetree-org/dt-schema/blob/cb53a16a1eb3e2169ce170c071e47940845ec26e/schemas/gpio/gpio-consumer.yaml#L20 Fixes errors such as: OF: /palmbus@300000/gpio@600: could not find phandle Fixes: 7f00be96 ("of: property: Add device link support for interrupt-parent, dmas and -gpio(s)") Signed-off-by:

The iio-bindings.txt was converted into two files and merged at the dt-schema git tree at: https://github.com/devicetree-org/dt-schema Yet, some documents still refer to the old file. Fix their references, in order to point to the right URL. Fixes: dba91f82 ("dt-bindings:iio:iio-binding.txt Drop file as content now in dt-schema") Acked-by:

As documents have been renamed and moved around, their references will break, but this will be unnoticed, as the script which checks for it won't handle "../" references. So, replace them by the full patch. Signed-off-by:
