Xilinx LLTEMAC driver issues

Fri Apr 4 22:54:01 EST 2008

Dear Ming,

I've made this test on EDK 9.2 + ll_temac 1.00.b + lltemac hw patch
(ftp://ftp.xilinx.com/pub/applications/misc/tx_ll_if_edk10_1.zip
(still up))+ ll_temac driver patch.
I'm currently working on a 10.1 rebase. (ongoing...)

Best regards,
Johann
