a1bc9b875b [PATCH] skge: fix stuck irq when fiber down
The PHY interrupt from the internal fiber is getting

64f6b64dfb [PATCH] skge: fiber support
Add support for older fiber versions of the SysKonnect board. These chipsets
use an internal PHY so they require special handling. The older sk98lin

513f533e3f [PATCH] skge: use NAPI for transmit complete
The skge driver has much better performance if transmit done is handled in
NAPI softirq. Change from doing transmit locking in driver (LLTX) and
use device lock.

7c442fa17e [PATCH] skge: transmit complete via IRQ not NAPI
The transmit side code has a number of ring problems that caused some
of the Bugzilla reports. Rather than trying to fix the details, it is safer
to rewrite the code that handles transmit completion and freeing.

to just compute the value (ala e1000). Don't need tes on link up

cfc3ed796e [PATCH] skge: use auto masking of irqs
Improve performance of skge driver by not touching irq mask
register as much. Since the interrupt source auto-masks, the driver
can just leave it disabled until the end of the soft irq.

 * change skge_xm_ to just xm_
 * fix xm_write32 to write as two u16's with correct byte order
