Well it looks like the fec driver has had a lot of changes since 2.6.30. No idea which might have broken it. I haven't tried 2.6.31 or 2.6.32 yet on the coldfire. I probably will soon (on a 5270 in my case). Certianly there appears to be changed related to receive. An rx_buff ring has been added (there was only a tx_buff ring before), along with other changes. -- Len Sorensen _______________________________________________ uClinux-dev mailing list uClinux-dev@uclinux.org http://mailman.uclinux.org/mailman/listinfo/uclinux-dev This message was resent by uclinux-dev@uclinux.org To unsubscribe see: http://mailman.uclinux.org/mailman/options/uclinux-dev
