Turns out we're freeing the skb when we detect CRC error, but we're
not clearing out info->skb. We could either clear it and have the stack
reallocate it, or just leave it and the rx ring refill code will reuse
the one that was allocated.
Reusing a freed skb obviously caused some nasty crashes of various kind,
as reported by Brent Baude and David Woodhouse.

Prevent deadlock in sky2 recovery logic. sky2_down calls napi_synchronize
which gets stuck if napi was already disabled.
Fix by rearranging slightly and not calling napi_disable until after
both ports are stopped. The napi_disable probably is being overly
paranoid, but it is safe now.

Using PCIE advanced error recovery stuff creates more user problems than it's worth.

Plip passes a string "name" that is allocated on stack to

"name" and when the registering function exits, it points nowhere.
On some machine, this bug causes bad names to appear in /proc, such as
/proc/sys/dev/parport/parport0/devices/T^/�X^/�, on others, the plip
proc node is completely missing.

netif_rx is meant to be called from interrupts because it doesn't wake
up ksoftirqd. For calling from outside interrupts, netif_rx_ni exists.
This fixes plip to use netif_rx_ni. It fixes the infamous error "NOHZ:
local_softirq_panding 08" that happens on some machines with NOHZ and
plip --- it is caused by the fact that softirq is pending and ksoftirqd
