[dpdk-dev] [PATCH v3] net/ixgbe: fix tunnel type set error for FDIR

Wei Zhao wei.zhao1 at intel.com
Thu Jun 14 10:17:28 CEST 2018


Tunnel type format should be translated to ixgbe required format
before register set in FDIR cloud mode, Ans also some register
not useful in cloud mode but only useful in IP mode should be set
to zero as datasheet request.

Fixes: 82fb702077f6 ("ixgbe: support new flow director modes for X550")
Fixes: 11777435c727 ("net/ixgbe: parse flow director filter")

v2:
-change register write function for FDIRIPSA and FDIRIPDA.

v3:
-add macros for 0x8000 and 0.
