Nope, missed those. Thx! At one level I hate it when I test something that is out of date, but losing a day of testing to only being a day out of date, is particularly annoying. :( As I noted, I'm in love with those routing cache lookup fixes in 4.x.... I have a (bad) patch for BQL for this driver too that could probably be fixed unless it landed already? (I am not sure how you do xmit_more without BQL) I will go back to testing on 4.1 on the archer for a while. The steps to reproduce the bug I saw is merely try running two or more copies of netperf to the router. > > > Imre > > > On Sat, 28 Nov 2015 15:41:17 +0100, Dave Taht <dave.t...@gmail.com> wrote: > >> I went for a test drive of openwrt DESIGNATED DRIVER (Bleeding Edge, >> r47665) today. >> >> A) I bricked the archer c7 v2.
