2020-03-13net/mlx5e: en_rep: Create uplink rep root table after eswitch offloads tablePaul Blakey1-0/+1
The eswitch offloads table, which has the reps (vport) rx miss rules, was moved from OFFLOADS namespace [0,0] (prio, level), to [1,0], so the restore table (the new [0,0]) can come before it. The destinations of these miss rules is the rep root ft (ttc for non uplink reps). Uplink rep root ft is created as OFFLOADS namespace [0,1], and is used as a hook to next RX prio (either ethtool or ttc), but this fails to pass fs_core level's check. Move uplink rep root ft to OFFLOADS prio 1, level 1 ([1,1]), so it will keep the same relative position after the restore table change.

Currently, if VF is loaded on the host side, the host doesn't clear the VF's VLAN table entries when VF removing. In this case, when doing reset and disabling sriov at the same time the VLAN device over VF will be removed, but the VLAN table entries in hardware are remained. This patch fixes it by asking PF to clear the VLAN table entries for VF when VF is removing. It also clears the VLAN table full bit after VF VLAN table entries being cleared.

This patch fixes an off-by-one error in strncpy size argument in drivers/net/ethernet/samsung/sxgbe/sxgbe_main.c. The issue is that in: strncmp(opt, "eee_timer:", 6) the passed string literal: "eee_timer:" has 10 bytes (without the NULL byte) and the passed size argument is 6. As a result, the logic will also accept other, malformed strings, e.g. "eee_tiXXX:". This bug doesn't seem to have any security impact since its present in module's cmdline parsing code.
