Xen devel - Dec 2011 - linux 3.1.0 - no network offload

I''ve just noticed that all the offloads on my vif interfaces are
disabled and I can''t enable them. Has something changed in the later
kernels?

Thanks

It''s hard to say unless you provide details like which kernel are you
using. Do you know which baseline last worked for you?

Are you talking about the vif device in dom0 or the endpoint inside the
guest or both?

47103041e91794acdbc6165da0ae288d844c820b is the only upstream netback
which springs out as being related. IIRC
d0e5d83284dac15c015bb48115b6780f5a6413cd is a fixup for that commit
relating to migration.

The contents of the front and backend directories in xenstore might be
interesting?

I upgraded my Debian kernel and all the problems went away. It was also obscured
by a bug in my GPLPV drivers that wasn''t reading the ''checksum
offload enabled'' flag from the registry properly which caused problems
of its own, but the linux PV DomU''s were also misbehaving.
