[Arm-dev] [PATCH 28/30] net: thunderx: Fix configuration of L3/L4 length checking

[mohun106 at gmail.com]

From: Sunil Goutham <sgoutham at cavium.com>

This patch fixes enabling of HW verification of L3/L4 length and
TCP/UDP checksum which is currently being cleared. Also fixed VLAN
stripping config which is being cleared when multiqset is enabled.
