skb->dev is being unnecessarily set by the driver on packet recieve.
eth_type_trans already sets skb->dev to the proper value and it is not
referenced anywhere else in the dirver, thus making its setting unnecessary.

Driver appears to be mistaking the permission field with default value
in the case of debug and qlge_irq_type.

Driver is also passing debug as a bitmask into netif_msg_init()
which wants a number of bits.  Ron Mercer suggests we should
change this to pass in -1 so the defaults get used instead,
which makes the default much less verbose.

Many (but not all) drivers check to see whether there is a vlan
group configured before using a tag stored in the skb.  There's
not much point in this check since it just throws away data that
should only be present in the expected circumstances.  However,
it will soon be legal and expected to get a vlan tag when no
vlan group is configured, so remove this check from all drivers
to avoid dropping the tags.

Currently qlge can deadlock when the interface is going
down, and the mpi_port_cfg_work() is executing on another
processor. It happens because unregister_netdev() holds
the rtnl lock, and the mpi_port_cfg_work() also request
this lock.

Since unregiter_netdev() may wait mpi_port_cfg_work(), who
also request the holding lock, it can cause an deadlock,
displaying the following error:

 "echo 0 > /proc/sys/kernel/hung_task_timeout_secs" disables this message.
