[dpdk-dev] [PATCH] net/igb: fix add/delete of flex filters

[Markus Theil]

Before this patch, flex_filter->index was always zero when it was read
and used after rte_zmalloc. The corresponding code was therefore moved into the add
and delete parts of the if/else statement. i210 and i211 also support
flex filters.

Thanks for the patch. To my opinion, there're 2 things here. One is to support the flex filter on i210/i211. The other is to fix the index issue.
Would you like to split it to 2 patches? So you can add a fixes tag for the index one.
