It would be great to be able to get my board working with the sk driver.

The board is a SysKonnect SK-9844 v1 board (2 x fibre ports).  The
SysKonnect YK driver works fine under 5.2, but as I need to run a 5.3-RC
version I can't use the board until they release a 5.3 version of the
driver.
The SK driver in FreeBSD always reports "skc0: no PHY found!".

Boot info with this patch loaded is as follows:

5.3-BETA6

skc0: <SysKonnect Gigabit Ethernet (V1.0)> port 0xb800-0xb8ff mem
0xf55fc000-0xf55fffff irq 24 at device 2.0 on pci2
