[dpdk-dev] [PATCH 05/13] net/bnxt: return proper error code

[Ajit Khaparde <ajit.khaparde@broadcom.com>]

If the FW fails bnxt_hwrm_func_reset() with an error status,
instead of returning -1, return a more standard value of -EIO.
Similarly sometimes the status returned by certain FW commands
may not be generic. Return a more standard value of -EIO in
that case as well.
