intel-ethernet: clean up W=1 warnings in kdoc

2020-09-25T23:28:59Z

This takes care of all of the trivial W=1 fixes in the Intel Ethernet drivers, which allows developers and maintainers to build more of the networking tree with more complete warning checks. There are three classes of kdoc warnings fixed: - cannot understand function prototype: 'x' - Excess function parameter 'x' description in 'y' - Function parameter or member 'x' not described in 'y' All of the changes were trivial comment updates on function headers. Inspired by Lee Jones' series of wireless work to do the same.

net: intel: Cleanup the copyright/license headers

2018-04-27T18:00:04Z

After many years of having a ~30 line copyright and license header to our source files, we are finally able to reduce that to one line with the advent of the SPDX identifier. Also caught a few files missing the SPDX license identifier, so fixed them up.

i40e: reduce wait time for adminq command completion

2017-04-20T00:38:25Z

When sending an adminq command, we wait for the command to complete in a loop. This loop waits for an entire millisecond, when in practice the adminq command is processed often much faster. Change the loop to use i40e_usec_delay instead, and wait for 50 usecs each time instead. This appears to be about the minimum time required, based on some manual observation and testing. The primary benefit of this change is reducing latency of various operations in the PF driver, especially when related to having a large number of VFs enabled. For example, on Linux, when instantiating 128 VFs, the time to finish the operation dropped from about 9 seconds down to under 6 seconds. Additionally, the time it takes to finish a PF reset with 128 VFs dropped from 5.1 seconds down to 0.7 seconds. As the examples above show, a significant portion of the delay is wasted waiting for admiqn operations which have already finished. This patch shouldn't cause impact to functionality, as we still check and keep waiting until the command does get processed. The only expected change is an increase in CPU utilization as we now check for completion far more times. However, in practice the commands appear to generally be complete within the first delay window anyways.

The error code sent into i40e_aq_rc_to_posix() are signed values, so we really need to treat them as such. Change-ID: I3d1ae0ee9ae0b1b6f5fc424f8b8cc58b0ea93203 Reported-by: Helin Zhang Signed-off-by: Shannon Nelson Tested-by: Andrew Bowers Signed-off-by: Jeff Kirsher

i40e/i40evf: print FW build number in version string

2015-03-03T09:07:24Z

Include the FW build number in the formatted FW version string. In order to fit within ethtool's 32 character limit, the etrack's unused high order bits are trimmed as is the leading 0 for the NVM version. This leaves us with 2 character left for if/when the etrack id goes to 5 hex chars and the NVM major number goes to 2 chars.
