2023-12-18intel: legacy: field get conversionJesse Brandeburg
Refactor several older Intel drivers to use FIELD_GET(), which reduces lines of code and adds clarity of intent. This code was generated by the following coccinelle/spatch script and then manually repaired. @get@ constant shift,mask; type T; expression a; @@ ( -((T)((a) & mask) >> shift) +FIELD_GET(mask, a) and applied via: spatch --sp-file field_prep.cocci --in-place --dir \ drivers/net/ethernet/intel/ Cc: Julia Lawall <Julia.Lawall@inria.fr> CC: Alexander Lobakin <aleksander.lobakin@intel.com> Reviewed-by: Marcin Szycik <marcin.szycik@linux.intel.com> Reviewed-by: Simon Horman <horms@kernel.org> Signed-off-by: Jesse Brandeburg <jesse.brandeburg@intel.com> Tested-by: Pucha Himasekhar Reddy <himasekharx.reddy.pucha@intel.com> (A Contingent worker at Intel) Signed-off-by: Tony Nguyen <anthony.l.nguyen@intel.com>
2018-11-07igbvf: Replace spin_is_locked() with lockdepLance Roy
lockdep_assert_held() is better suited to checking locking requirements, since it won't get confused when someone else holds the lock. This is also a step towards possibly removing spin_is_locked().

2018-04-27net: intel: Cleanup the copyright/license headersJeff Kirsher
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.

2017-08-08igbvf: add lock around mailbox opsGreg Edwards
The PF driver assumes the VF will not send another mailbox message until the PF has written its reply to the previous message. If the VF does, that message will be silently dropped by the PF before it writes its reply to the mailbox. This results in a VF mailbox timeout for posted messages waiting for an ACK, and the VF is reset by the igbvf_watchdog_task in the VM. Add a lock around the VF mailbox ops to prevent the VF from sending another message while the PF is still processing the previous one.

2016-02-15igb/igbvf: don't give upMitch Williams
The driver shouldn't just give up if it fails to get the hardware mailbox lock. This can happen in a situation where the PF-VF communication channel is heavily loaded and causes complete communications failure between the PF and VF drivers. Add a counter and a delay. The driver will now retry ten times, waiting one millisecond between retries.

2015-02-23igbvf: Fix code comments and whitespaceJeff Kirsher
Fix the code comments to align with the drivers/net/ commenting style. Also fix other checkpatch errors such as using tabs where possible and properly wrap lines to conform to the 80 char limit (unless it is a string).
