[dpdk-dev] [PATCH] net/octeontx2: fix vlan filter on port

[psatheesh at marvell.com]

From: Satheesh Paul <psatheesh at marvell.com>

This patch fixes incorrect MCAM key preparation when creating
MCAM entry to allow VLAN IDs after vlan filtering is enabled on port.

Fixes: ba1b3b081e ("net/octeontx2: support VLAN offloads")
