[PATCH 0/1] Treat IPv6 diffserv the same as ipv4 diffserv for 802.11e

[PATCH 0/1] Treat IPv6 diffserv the same as ipv4 diffserv for 802.11e

[Dave Taht]

This treats ipv6 and ipv4 the same, on wireles, where diffserv is
concerned.

I note that it would be nice if this mechanism tossed packets marked
with the interactive bit into the VI queue as well. Nicer still
would be a more generic and comprehensive diffserv handling.

[PATCH 1/1] Treat IPv6 diffserv the same as ipv4 diffserv for 802.11e

[Dave Taht]

Wireless will select a different hardware queue based on the
top 3 bits of the diffserv field, for ipv4. Extend that queue
selection mechanism to ipv6, and make the calls orthogonal.

The patch itself seems fine to me.  But the format needs work:

Would you mind fixing-up the email and resubmitting?
