From: Xianting Tian <xianting.tian@linux.alibaba.com> stable inclusion from linux-4.19.198 commit 34218ccb387c1e5e94b2baa6e337fb0367edede0 -------------------------------- [ Upstream commit 85eb1389458d134bdb75dad502cc026c3753a619 ] We should not directly BUG() when there is hdr error, it is better to output a print when such error happens. Currently, the caller of xmit_skb() already did it. Signed-off-by: Xianting Tian <xianting.tian@linux.alibaba.com> Reviewed-by: Leon Romanovsky <leonro@nvidia.com> Signed-off-by: David S.
