Greetings:

I've been alerted to an interoperability issue with the cicada cis8201 (now the vitesse vsc8201) gigabit ethernet phy and the Intel 82547EI.

Apparently the Intel part has a 'slightly delayed response' in making the scrambler mode detection.

This patch lengthens the timer setting for the '8201.

I have had a report or two of problems with link on the Ocotea (IBM440GX reference design) which uses the '8201.

CHANGELOG Entry:

* Patch by Travis Sawyer, 23 Apr 2004: Fix VSC/CIS 8201 phy descrambler interoperability timing due to errata from Vitesse Semiconductor.

Patch is attached.

Best Regards,

Travis Sawyer
