Hi Greg,

Hi Nathan,

I am so sorry I didn't catch this in my initial report but this
commit
along with ba7aaf93ef2f ("netlink: Don't shift with UB on nlk-

quoted

ngroups")

breaks mobile data on both the Pixel 2 XL and OnePlus 6. There is
signal
but it just never connects to 3G/LTE. Reverting those two commits
fixes
the issue.

Sorry for breaking your use-case,

Nothing stands out to me in dmesg unfortunately and iven neither
device
is running a vanilla kernel, I cannot say if this is a problem in
mainline
or not but I just wanted to make you aware of it.

Could you provide the dmesg output for the attached debug diff?
