> Subject: [Intel-wired-lan] [PATCH] igc: Fix default MAC address filter override
> This patch fixes a bug when the user adds the first MAC address filter
> via ethtool NFC mechanism.
> When the first MAC address filter is added, it overwrites the default
> MAC address filter configured at RAL[0] and RAH[0]. As consequence,
> frames addressed to the interface MAC address are not sent to host
> anymore.
> This patch fixes the bug by calling igc_set_default_mac_filter() during
> adapter init so the position 0 of adapter->mac_table[] is assigned to
> the default MAC address.
