[dpdk-dev] [PATCH 18/22] net/bnxt: pass correct RSS table address for thor

[Ajit Khaparde]

From: Lance Richardson <lance.richardson at broadcom.com>

The current implementation erroneously passes the address of the
beginning of RSS table for each 64-entry context instead of the
address of the appropriate subtable for the context. This results
in only the first 64 receive queues being used. Fix by passing the
correct address for each context.

Fixes: 38412304b50a ("net/bnxt: enable RSS for thor-based controllers")
