I have noted that the e1000 driver is now supporting DMA splitting of
the packet header and payload into separate pages. I also noticed
that none of the config options enable it. Is anyone using this feature
at present and has it even been tested on Linux?
The 6.2.15 driver off http://prdownloads.sf.net/e1000 will enable it
by default. We've gone through our release approval, which includes
quite a bit of testing.
If the patches posted recently don't include that support, I missed
something :-)
This is only on the 82571 and greater hardware that packet split is
supported, BTW.
Got it. I am merging packet capture support into the e1000 for DSFS for
direct cache DMA support. I noticed the two distinct fill routines
for the ring buffer. I have enabled DSFS for both with this driver. I
will post patches late tonight or in the morning for the 82571 support
for DSFS. I will
also be posting the patches for 2.6.12, 2.6.10. 2.6.14, Suse 9 and 10.0,
Red Hat ES/AS 3 and 4, and Fedora Core 2/3/4 by end of week with the
packet splitting capabilities with packet capture on DSFS. This is a
very good optimization and should come in handy for reducing header copies
in the protocol stacks.
