Only set the devices_in_package to a non-zero value if we find a valid value for this field, so we avoid leaving it set to e.g. 0x1fffffff. Reviewed-by:

Add support for probing MMDs above 7 for a valid devices-in-package specifier, but only probe the vendor MMDs for this if they also report that there the device is present in status register 2. This avoids issues where the MMD is implemented, but does not provide IEEE 802.3 compliant registers (such as the MV88X3310 PHY.) Reviewed-by:

Reword the get_phy_device() kerneldoc to be more explicit about how we probe for the PHY, and what the various return conditions signify. Reviewed-by:

Move the ID check from get_phy_device() into get_phy_c22_id(), which simplifies get_phy_device(). The ID reading functions are now responsible for indicating whether they found a PHY or not via their return code - they must return -ENODEV when a PHY is not present. Reviewed-by:

When we decide that a PHY is not present, we do not need to go through the hoops of setting *phy_id to 0xffffffff, and then return zero to make get_phy_device() fail - we can return -ENODEV which will have the same effect. Doing so means we no longer have to pass a pointer to phy_id in, and we can then clean up the clause 22 path in a similar way. Reviewed-by:

Rearrange the code to read the PHY IDs, so we don't call get_phy_id() only to immediately call get_phy_c45_ids(). Move that logic into get_phy_device(), which results in better readability. Reviewed-by:

Move the Cortina PHY workaround out of the "devices in package" loop; it doesn't need to be in there as the control flow will terminate the loop once we enter the workaround irrespective of the workaround's outcome. The workaround is triggered by the ID being mostly 1's, which will in any case terminate the loop. Signed-off-by:

This patch adds a drop frames counter to tc flower offloading. Reporting h/w dropped frames is necessary for some actions. Some actions like police action and the coming introduced stream gate action would produce dropped frames which is necessary for user. Status update shows how many filtered packets increasing and how many dropped in those packets. v2: Changes - Update commit comments suggest by Jiri Pirko. Signed-off-by:

Chelsio adapter contains different flash regions and each region is used by different binary files. This patch adds support to flash images like PHY firmware, boot and boot config using ethtool -f N. The N value mapping is as follows. N = 0 : Parse image and decide which region to flash N = 1 : Firmware N = 2 : PHY firmware N = 3 : boot image N = 4 : boot cfg Signed-off-by: Vishal Kulkarni <vishal@chelsio.com>" Signed-off-by: -

Eric Dumazet says: ==================== net: tso: expand to UDP support With QUIC getting more attention these days, it is worth implementing UDP direct segmentation, the same we did for TCP. Drivers will need to advertize NETIF_F_GSO_UDP_L4 so that GSO stack does not do the (more expensive) segmentation. Note the two first patches are stable candidates, after tests confirm they do not add regressions. v2: addressed Jakub feedback : 1) Added a prep patch for octeontx2-af 2) calls tso_start() earlier in otx2_sq_append_tso() ==================== Signed-off-by: -

Transport header size could be 60 bytes, and network header size can also be 60 bytes. Add the Ethernet header and we are above 128 bytes. Since drivers using net/core/tso.c usually allocates one DMA coherent piece of memory per TX queue, this patch might cause issues if a driver was using too many slots. For 1024 slots, we would need 256 KB of physically contiguous memory instead of 128 KB. Alternative fix would be to add checks in the fast path, but this involves more work in all drivers using net/core/tso.c.

We need to increase TSO_HEADER_SIZE from 128 to 256. Since otx2_sq_init() calls qmem_alloc() with TSO_HEADER_SIZE, we need to change (struct qmem)->entry_sz to avoid truncation to 0. Fixes: 7a37245e ("octeontx2-af: NPA block admin queue init") Signed-off-by:

Right now they are empty functions for our SoC since hardware can keep cache coherent, but it is still good to align with streaming DMA APIs as device drivers should not make an assumption of SoC. Reviewed-by:
