[dpdk-dev] [PATCH 11/17] net/qede: fix flow director bug for IPv6 filter

[Rasesh Mody]

From: Shahed Shaikh <shahed.shaikh at cavium.com>

- PMD does not fill vtc_flow field of IPv6 header while
  constructing a packet for IPv6 filter. Hence filter was
  not getting applied properly.
- IPv6 addresses got swapped while copying src and dst addresses.
- Same issue with UDP and TCP port ids.

Fixes: 622075356e8f ("net/qede: support ntuple and flow director filter")
