net/mlx4_core: Fix VF overwrite of module param which disables DMFS on new probed PFs
[ Upstream commit 95f1ba9a24af9769f6e20dfe9a77c863f253f311 ]
In the VF driver, module parameter mlx4_log_num_mgm_entry_size was
mistakenly overwritten -- and in a manner which overrode the
device-managed flow steering option encoded in the parameter.
log_num_mgm_entry_size is a global module parameter which
affects all ConnectX-3 PFs installed on that host.
If a VF changes log_num_mgm_entry_size, this will affect all PFs
which are probed subsequent to the change (by disabling DMFS for
those PFs).
Fixes: 3c439b5586e9 ("mlx4_core: Allow choosing flow steering mode")
