Can you explain why the ti(4) driver needs a coalescing patch? It already
has in-firmware coalescing paramters that are tuneable by the user. It
also already processes all outstanding BDs in ti_rxeof() and ti_txeof().
It isn't terribly clear what you're doing in the patch, since it isn't a
You also never gave any details behind your statement last week:
"Because at the time the Tigon II was released, the jumbogram
wire format had not solidified. Therefore cards built during
that time used different wire data for the jumbogram framing."
I asked, in response:
"Can you give more details? Did someone decide on a different ethertype
than 0x8870 or something?
That's really the only thing that's different between a standard ethernet
frame and a jumbo frame. (other than the size)"
