IPv6 issues...

Backported with help of the Oleg's firmware folks the cdc mbim driver to an even older kernel (late-2.6).

It works perfectly for ipv4-only devices. Dual stacked (IPv6 is turned off in the kernel) devices gets the NDP offset wrong.

Anyone recognise this weird behaviour?

Ive set the buffers via /proc to a maximum already.

The BPF cannot catch the packets so I guess it is on an even lower level in the rxpath.
