Subject: net: mvpp2: prs: Drop unnecessary swab16 in vlan detection
Patch-mainline: v4.19-rc1
Git-commit: 432b59426bcaf217137a27c384bc1d215946912d
References: bsc#1119113 FATE#326472

Vlan IDs must not be swapped when creating Header Parser entries. This
has no effect on little-endian systems, but is wrong for big-endian.
