[Intel-wired-lan] [Patch v1 13/20] ice: Add GTPU FDIR filter for AVF

Haiyue Wang haiyue.wang at intel.com
Thu Jan 14 11:13:03 UTC 2021


From: Qi Zhang <qi.z.zhang at intel.com>

Add new FDIR filter type to forward GTPU packets by matching TEID or QFI.
The filter is only enabled when COMMS DDP package is downloaded.
