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
