net/tstun: probe TCP GRO (#13376) Disable TCP & UDP GRO if the probe fails. torvalds/linux@e269d79c7d35aa3808b1f3c1737d63dab504ddc8 broke virtio_net TCP & UDP GRO causing GRO writes to return EINVAL. The bug was then resolved later in torvalds/linux@89add40066f9ed9abe5f7f886fe5789ff7e0c50e. The offending commit was pulled into various LTS releases. Updates #13041 Signed-off-by: Jordan Whited <jordan@tailscale.com> 2024-09-05 09:59:31 -07:00			`func (t *Wrapper) SetLinkFeaturesPostUp() {}`
