Peter Wemm fe63158271 Changes to the Digi/Arnet SYNC driver: ... 1. Create 2 x 8k transmit buffer blocks in place of the 16k block previously. With this change the speed as tested with ttcp on a 2Mbit link went up from 206kbyte/s to 236kbyte/s. 2. Change the rest of the functions to also have the definition of the return value on a sepperate line. 3. Remove some unused variables. 4. Add code to recover from DMA underruns. 5. Reorder ar_get_packets() to handle errors better. 6. Only allocate a mbuf cluster if the data is more than the mbuf. (and in a second diff in addition to the above) 7. Stops the occasional DMA underruns that occurred when 2 channels are running at 2Mbit/s. Submitted by: John Hay <jhay@mikom.csir.co.za>		1996-03-17 00:29:35 +00:00
