[dpdk-dev] [PATCH v2 3/5] net/qede: fix PF fastpath status block index

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

From: Harish Patil <harish.patil@qlogic.com>

Allocate double the number of fastpath status block index
since the PF RX/TX queues are not sharing the status block.
This is an interim solution till other parts of the code
is modified to handle the same.

Fixes: f1e4b6c0acee ("net/qede: fix status block index for VF queues")
