RDMA/bnxt_re: HW workarounds for handling specific conditions
This patch implements the following HW workarounds
1. The SQ depth needs to be augmented by 128 + 1 to avoid running
into an Out of order CQE issue
2. Workaround to handle the problem where the HW fast path engine continues
to access DMA memory in retranmission mode even after the WQE has
already been completed. If the HW reports this condition, driver detects
it and posts a Fence WQE. The driver stops reporting the completions
to stack until it receives completion for Fence WQE.
