Subject: [PATCH] qlge: Fix incorrect usage of module parameters and netdev
 msg level

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.
