[dpdk-dev] [PATCH] net/qede/base: fix to initialize HW for LLH filters

[dpdk-dev] [PATCH] net/qede/base: fix to initialize HW for LLH filters

[Mody, Rasesh]

During initalization of leading PF, we need to initialize HW for LLH
filters. Set HW init parameter to set the eingine affinity for
multiple engine adapters.

Fixes: 3eed444a9621 ("net/qede/base: changes for 100G")

Applied to dpdk-next-net/master, thanks.
