`if (x != 0)` is basically a more verbose version of `if (x)` so let's use the latter so it's consistent throughout the whole driver. Reviewed-by:

The == operator precedes the || operator, so we can remove the parenthesis around (a == b) || (c == d). The condition is rather explicit and short so removing the parenthesis definitely does not make it harder to read. Reviewed-by:

Microsemi PHYs (VSC 8530/31/40/41) need to update the Energy Efficient Ethernet initialization sequence. In order to avoid certain link state errors that could result in link drops and packet loss, the physical coding sublayer (PCS) must be updated with settings related to EEE in order to improve performance.

There are a few counters available in the PHY: receive errors, false carriers, link disconnects, media CRC errors and valids counters. So let's expose those in the PHY driver. Use the priv structure as the next PHY to be supported has a few additional counters. Reviewed-by:

The Microsemi PHYs have multiple banks of registers (called pages). Registers can only be accessed from one page, if we need a register from another page, we need to switch the page and the registers of all other pages are not accessible anymore. Basically, to read register 5 from page 0, 1, 2, etc., you do the same phy_read(phydev, 5); but you need to set the desired page beforehand. In order to guarantee that two concurrent functions do not change the page, we need to do some locking per page. This can be achieved with the use of phy_select_page and phy_restore_page functions but phy_write/read calls in-between those two functions shall be replaced by their lock-free alternative __phy_write/read. Let's migrate this driver to those functions. Suggested-by:

There is no need to compare *val.vu32* with < 0 because such variable is of type u32 (32 bits, unsigned), making it impossible to hold a negative value. Fix this by removing such comparison. Also, initialize variable *max_val* to -1, just in case it is not initialized to either BNXT_MSIX_VEC_MAX or BNXT_MSIX_VEC_MIN_MAX before using it in a comparison with val.vu32 at line 159: if (val.vu32 > max_val) Addresses-Coverity-ID: 1473915 ("Unsigned compared against 0") Addresses-Coverity-ID: 1473920 ("Uninitialized scalar variable") Signed-off-by:Gustavo A.

iwl_fw_dbg_collect can be called by any function that already has the error string ready. iwl_fw_dbg_collect_trig, on the other hand, does string formatting. The occurrences decrement is at iwl_fw_dbg_collect_trig, instead of iwl_fw_dbg_collect, which causes it to sometimes be skipped. Move it to the right location. Signed-off-by:

For trigger-based PPDUs, most values aren't part of the HE-SIG-A because they're preconfigured by the trigger frame. However, we still have this information since we used the trigger frame to configure the hardware, so we can (and do) read it back out and can thus show it in radiotap. Signed-off-by:

With NICs that don't read the NVM directly and instead rely on getting the relevant data from the firmware, the number of reserved MAC addresses was not added to the API. This caused the driver to assume there is only one address which results in all interfaces getting the same address. Update the API to fix this. While at it, fix-up the comments with firmware api names to actually match what we have in the firmware. Fixes: e9e1ba3d ("iwlwifi: mvm: support getting nvm data from firmware") Signed-off-by:

If all free RB queues are empty, the driver will never restock the free RB queue. That's because the restocking happens in the Rx flow, and if the free queue is empty there will be no Rx. Although there's a background worker (a.k.a. allocator) allocating memory for RBs so that the Rx handler can restock them, the worker may run only after the free queue has become empty (and then it is too late for restocking as explained above). There is a solution for that called 'emergency': If the number of used RB's reaches half the amount of all RB's, the Rx handler will not wait for the allocator but immediately allocate memory for the used RB's and restock the free queue. But, since the used RB's is per queue, it may happen that the used RB's are spread between the queues such that the emergency check will fail for each of the queues (and still run out of RBs, causing the above symptom). To fix it, move to emergency mode if the sum of *all* used RBs (for all Rx queues) reaches half the amount of all RB's Signed-off-by:
