It is better to change the behaviour only for the misbehaving device,
as it is done with this alternative.

However as far as I understand, the change is removing a long delay due
to the reset, but re-enable a security hole due to the lack of reset.
So I think we must have a compilation option anyway, in order to let
the packager (or distribution) make this difficult decision.
The compilation option could be something like
	RTE_BNX2X_PREFER_SECURITY_HOLE_THAN_LONG_RESTART
Feel free to find a better name :)
