I'm happy to report, that the version of the sky2 driver in 2.6.17-rc1
yields line rate at low CPU utilization (as determined using ttcp).
Unfortunately, it's not quite bug-free yet ;-}
When enabling the second interface (of the same network controller) the
kernel panics (perhaps during DHCP discovery?):

The kernel is vanilla 2.6.17-rc1, the sky2 driver was compiled into the
kernel. OS is RedHat Fedora Core 4. The kernel was compiled using
gcc32.
The system is a Blade of a BladeRunner 4130 of Penguincomputing, it
contains two Xeon CPU (+ HT enabled) and an on-board 8062 network
controller of Marvell (88E8062 is stamped on the chip).
The hardware seems to work fine using 2.6.15(.7) with the sk98lin driver
version 8.31 of Syskonnect (skd.de).
Please let me know, if I can provide further information or assist in
any other way.
best regards
Guenther
