[dpdk-dev] [PATCH] net/qede: fix L2-handles used for RSS hash update

[Rasesh Mody <rasesh.mody@cavium.com>]

Fix fast path array index which is used for passing L2 handles to RSS
indirection table. Currently, it is using the local copy of indirection
table. When the RX queue configuration changes the local copy becomes
invalid.
