Hi

What determines the queue size for the ethernet drivers. I have a Tigon
based 3com Gb card, and looses packets due to QFULL with error ENOBUFS.

However, monitoring the queue length, I see that it is sometimes empty
which could indicate a lowerloss eate with a longer queue.

The queue length is set by  
	TI_TX_RING_CNT_512 (512)
(subtracted 1) in the /sys/dev/pci/if_ti.c file

Can this limit be increased?
