Hi,
Please find attached and pasted below patch for ppc405_enet.c for comments.
The bk tree at source.mvista.com was based on 2.4.18-pre7 today when I
picked it up.
One change involves setting the flags for EMAC_IER, the manual does not
mention any defaults hence using 0 for it did not seem appropriate.
The second is a minor change of stats as the code uses transmit channel
0, the check for flag in ISR ought to be for the same.
Regards
Amit
