Using OpenWrt with kernels 5.2+ results in broken network. Interfaces
seem OK but I cannot ping my router anymore.

This regression is caused by the upstream commit

commit b424e432e770d6dd572765459d5b6a96a19c5286 (refs/bisect/bad)

    netlink: add validation of NLA_F_NESTED flag

Reverting that commit from the top of 5.2 or 5.3 fixes network for me.

Any ideas what's wrong with OpenWrt & above change?
