[dpdk-dev] [PATCH 3/3] net/bnxt: do not corrupt RSS hash value in the mbuf

[Kalesh A P]

From: Venkat Duvvuru <venkatkumar.duvvuru at broadcom.com>

By clearing mbuf->hash.fdir.id in the data path, the driver is
corrupting the RSS hash value populated in the mbuf as they
are defined as a union.

This patch fixes the problem by removing the code that clears
mbuf->hash.fdir.id.

Fixes: 17b6c8386d73 ("net/bnxt: fix mark handling")
