[PATCH] skge: handle out of memory on ring changes

[PATCH] skge: handle out of memory on ring changes

Please consider this for 2.6.15.1; it fixes several cases where
the skge driver can get in a bad state and later crash; if an
admin operation that causes a restart fails from out of memory.
Such as changing the MTU or increasing the ring size.

The fixes involve checking the return value and doing necessary
unwinds. Or in some cases avoiding doing a full restart.

The same code is the netdev-2.6 tree for 2.6.16 but as separate pieces
