Subject: RE: [PATCH 3/7]: [NET]: Do not check netif_running() and carrier state in ->poll()

Dave,

This change is not required as the macro, is_s2io_card_up() checks for
an internal state of the adapter and not netif's state. We want to make
sure that the adapter registers are not accessed when the adapter is
being brought down.
