2023-12-18igc: field get conversionJesse Brandeburg1-4/+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]>
2023-01-03igc: remove I226 Qbv BaseTime restrictionMuhammad Husaini Zulkifli1-0/+29
Remove the Qbv BaseTime restriction for I226 so that the BaseTime can be scheduled to the future time. A new register bit of Tx Qav Control (Bit-7: FutScdDis) was introduced to allow I226 scheduling future time as Qbv BaseTime and not having the Tx hang timeout issue. Besides, according to datasheet section 7.5.2.9.3.3, FutScdDis bit has to be configured first before the cycle time and base time. Indeed the FutScdDis bit is only active on re-configuration, thus we have to set the BASET_L to zero and then only set it to the desired value. Please also note that the Qbv configuration flow is moved around based on the Qbv programming guideline that is documented in the latest datasheet.

2022-05-10igc: Remove unused phy_type enumSasha Neftin1-2/+0
Complete to commit 8e153faf5827 ("igc: Remove unused phy type") i225 parts have only one PHY. There is no point to use phy_type enum. Clean up the code accordingly, and get rid of the unused enum lines.

2021-10-29igc: Change Device Reset to Port ResetSasha Neftin1-1/+1
The _reset_hw_base method switched from port reset (CTRL[26]) to device reset (CTRL[29]) since the FW was receiving an interrupt on CTRL[29]. FW code was later modified to also receive an interrupt on CTRL[26]. Since certain HW values are not reset to default by CTRL[29], we go back to CTRL[26] for the HW reset, as it meets all current requirements. This reverts commit bb4265ec24c1 ("igc: Update the MAC reset flow").

2021-10-29igc: Remove media type checking on the PHY initializationSasha Neftin1-5/+0
i225 devices only have copper phy media type. There is no point in checking phy media type during the phy initialization. This patch cleans up a pointless check.
