[PATCH 2/2] vti6: do not check for ignore_df in order to update pmtu

2018-08-30 Thread Thadeu Lima de Souza Cascardo
Before commit d6990976af7c5d8f55903bfb4289b6fb030bf754 ("vti6: fix PMTU caching and reporting on xmit"), skb was scrubbed before checking for ignore_df. The scrubbing meant ignore_df was false, making the check irrelevant. Now that the scrubbing happens after that, some packets might fail the check
