2023-12-18igc: field get conversionJesse Brandeburg1-3/+2
Refactor the igc driver to use FIELD_GET() for mask and shift reads, which reduces lines of code and adds clarity of intent. This code was generated by the following coccinelle/spatch script and then manually repaired in a later patch. @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 <[email protected]> Reviewed-by: Marcin Szycik <[email protected]> Reviewed-by: Simon Horman <[email protected]> Signed-off-by: Jesse Brandeburg <[email protected]> Signed-off-by: Tony Nguyen <[email protected]>
2023-12-18intel: add bit macro includes where neededJesse Brandeburg1-0/+1
This series is introducing the use of FIELD_GET and FIELD_PREP which requires bitfield.h to be included. Fix all the includes in this one change, and rearrange includes into alphabetical order to ease readability and future maintenance. virtchnl.h and it's usage was modified to have it's own includes as it should. This required including bits.h for virtchnl.h. Reviewed-by: Marcin Szycik <[email protected]> Signed-off-by: Jesse Brandeburg <[email protected]> Signed-off-by: Tony Nguyen <[email protected]>
2023-03-21igc: Remove obsolete DMA coalescing codeSasha Neftin1-14/+5
DMA coalescing is not applicable for i225 parts. This patch comes to tidy up the driver code. Signed-off-by: Sasha Neftin <[email protected]> Tested-by: Naama Meir <[email protected]> Signed-off-by: Tony Nguyen <[email protected]>
2022-04-13igc: Fix infinite loop in release_swfw_syncSasha Neftin1-2/+9
An infinite loop may occur if we fail to acquire the HW semaphore, which is needed for resource release. This will typically happen if the hardware is surprise-removed. At this stage there is nothing to do, except log an error and quit.

2021-12-15igc: Fix typo in i225 LTR functionsSasha Neftin1-1/+1
The LTR maximum value was incorrectly written using the scale from the LTR minimum value. This would cause incorrect values to be sent, in cases where the initial calculation lead to different min/max scales.
