From 6fc7caa84e713f7627e171ab1e7c4b5be0dc9b3d Mon Sep 17 00:00:00 2001 From: Michael Chan Date: Fri, 17 Jan 2020 00:32:46 -0500 Subject: bnxt_en: Fix ipv6 RFS filter matching logic. Fix bnxt_fltr_match() to match ipv6 source and destination addresses. The function currently only checks ipv4 addresses and will not work corrently on ipv6 filters.
