igc: Fix up hw vlan ops

2022-10-17T03:37:39Z

Adapt 2796f7cab10785ef40efbba97ef67ab319c96e9c to igc(4) * Don't reset the entire adapter for vlan changes, fix up the problems * Remove the VFTA, this hardware doesn't seem to implement it Approved by: grehan Differential Revision: https://reviews.freebsd.org/D31979 (cherry picked from commit 2eaef8ec4af1f7576a1444180020e23d2e142107)

igc: remove unnecessary PHY ID checks

2022-10-17T03:37:22Z

I225 devices have only one PHY vendor. There is unnecessary to check _I_PHY_ID during the link establishment and auto-negotiation process, the checking also caused devices like i225-IT failed. This patch is to remove the mentioned unnecessary checking.

igc: Increase rx_buffer_size local variable to 32b

2022-05-20T16:37:55Z

Apply 6987c47569b377f4b6eba9966afdedfb1b39fca8 to igc. This is not expected to have any benefit on current parts with current observed PBA sizes but will avoid surprises if they are increased in future chips.

igc: Remove redundant IFCAP_VLAN_HWTAGGING check

2022-01-30T20:42:28Z

Match igb(4) as in f7926a6d0c10. From Vincenzo, this check is redundant to setup providing us an IGC_RXD_STAT_VP bit and would make for an unexpected condition if IFCAP_VLAN_HWTAGGING were not set but the tag was stripped, which would be passed up the stack breaking isolation.

net: iflib: fix vlan processing in the drivers

2022-01-27T22:32:58Z

The logic that sets iri_vtag and M_VLANTAG does not handle the case where the 802.11q VLAN tag is 0. Fix this issue across the iflib drivers. While there, also improve and align the VLAN tag check extraction, by moving it outside the RX descriptor loop, eliminating a local variable and additional checks.

igc: Use hardware routine for PHY reset

2021-11-13T01:14:09Z

Summary: The previously used software reset routine wasn't sufficient to reset the PHY if the bootloader hadn't left the device in an initialized state. This was seen with the onboard igc port on an 11th-gen Intel NUC. The software reset isn't used in the Linux driver so all related code has been removed. Tested on: Netgate 6100 onboard ports, a discrete PCIe I225-LM card, and an 11th-gen Intel NUC.

igc: correctly update RCTL when changing multicast filters.

2021-11-13T00:58:34Z

Fix clearing of bits in RCTL for the non-bpf/non-allmulti case. Update RCTL after modifying the multicast filter registers as per the Linux driver. This fixes LACP on igc interfaces, where incoming LACP multicasti control packets were being dropped.
