Subject: [PATCH net-next 06/16] bnxt_en: Do not accept fragments for aRFS flow steering.
Date: Sun, 26 Jan 2020 04:03:00 -0500	[thread overview]
Message-ID: <1580029390-32760-7-git-send-email-michael.chan@broadcom.com> (raw)
In-Reply-To: <1580029390-32760-1-git-send-email-michael.chan@broadcom.com>

In bnxt_rx_flow_steer(), if the dissected packet is a fragment, do not
proceed to create the ntuple filter and return error instead.  Otherwise
we would create a filter with 0 source and destination ports because
the dissected ports would not be available for fragments.
