[dpdk-dev] [PATCH] net/i40e: fix recreate a flexible FDIR rule failed

[Guinan Sun]

This patch fixes the failure of recreate flexible fdir rule.
The root cause is that the flex_mask_flag is not reset during
flow destroy and flow flush.

Fixes: 6ced3dd72f5f ("net/i40e: support flexible payload parsing for FDIR")
