[PATCH] driver/net/skge.c: Restart the interface when it's options or pauseparam is set

Hi,

We have an issue of the skge driver: The card won't work when it's options are
changed. That's the hardware info:
# lspci -v
05:04.0 Ethernet controller: Marvell Technology Group Ltd. 88E8001 Gigabit Ethernet Controller (rev 13)
Subsystem: Marvell Technology Group Ltd. Marvell RDK-8001
Flags: bus master, 66MHz, medium devsel, latency 32, IRQ 16
Memory at d042c000 (32-bit, non-prefetchable) [size=16K]
I/O ports at d000 [size=256]
[virtual] Expansion ROM at 20400000 [disabled] [size=128K]
Capabilities: [48] Power Management version 2
Capabilities: [50] Vital Product Data

The happens in both Linux-2.6.26(skge version 1.23) and RHEL5.2(skge version 1.6).


For example, at first it is set to "speed 1000 duplex full auto-neg on" and
it works, then run
ethtool -s <ethx> autoneg off
or ethtool -s <ethx> speed 100 duplex full autoneg off

Then it will stop working. After that if we restart the interface:
ifconifg <ethx> down
ifconfig <ethx> up
It will work again. And `ethtool -A' has the same issue.

So we think after setting the options, the interface should be restarted.
That's the patch, thank you.


skge: Restart the interface when it's options or pauseparam is set.
