Subject: bnx2x: bnx2fc: FC-NPIV table with bad length
I see the following error when booting a 4.4.1 kernel from the
bnx2x/bnx2fc drivers:
bnx2x: [bnx2x_get_fc_npiv:14843(eth2)]FC-NPIV table with bad length 0x08000040
This is using a QLogic/Broadcom CNA card in FCoE mode. The relavent code
in drivers/net/ethernet/broadcom/bnx2x/bnx2x_main.c has:
if (!tbl->fc_npiv_cfg.num_of_npiv) {
DP(BNX2X_MSG_MCP,
"No FC-NPIV table [valid, simply not present]\n");
goto out;
} else if (tbl->fc_npiv_cfg.num_of_npiv > MAX_NUMBER_NPIV) {
BNX2X_ERR("FC-NPIV table with bad length 0x%08x\n",
tbl->fc_npiv_cfg.num_of_npiv);
goto out;
} else {
DP(BNX2X_MSG_MCP, "Read 0x%08x entries from NVRAM\n",
tbl->fc_npiv_cfg.num_of_npiv);
}
where:
#define MAX_NUMBER_NPIV 64
It looks like some portion of fc_npiv_cfg.num_of_npiv needs to be
masked off. How much to mask requires a spec or perhaps just
max_npiv_vports? The same code is used in the 4.5 kernel.
