Subject: [ECOS] Ethernet driver question
Date: Wed, 29 Oct 2003 18:24:00 -0000	[thread overview]
Message-ID: <3FA005C0.7070804@rawbw.com> (raw)

Couple of silly questions, I like multiple choice: 

1) When the HDWR_Send function is called, is there:
  a) a valid FCS already at the end of the data?
  b) 4 bytes where the FCS should be, but expects the hardware to change 
it on the way out
  c) No FCS, expects the hardware to append an FCS

(Our hardware can generate an FCS, so would save some cycles if the FCS 
were not generated in software)

2) When HDWR_recv is called to get a packet, does it expect a valid enet 
frame including MAC address, and FCS on the end, or does it want those 
stripped off?  I imagine the former is correct, but I just want to make 
sure.


Thanks,

-John Newlin
