Subject: [PATCH v2 net-next 00/12] qed: Add iWARP support for unaligned MPA packets
Date: Tue, 3 Oct 2017 11:54:50 +0300 [thread overview]
Message-ID: <1507020902-4952-1-git-send-email-Michal.Kalderon@cavium.com> (raw)
This patch series adds support for handling unaligned MPA packets.
(FPDUs split over more than one tcp packet).
When FW detects a packet is unaligned it fowards the packet to
the driver via a light l2 dedicated connection. The driver then
stores this packet until the remainder of the packet is received.
Once the driver reconstructs the full FPDU, it sends it down
to fw via the ll2 connection. Driver also breaks down any packed
PDUs into separate packets for FW.
Patches 1-6 are all slight modifications to ll2 to support additional
requirements for the unaligned MPA ll2 client.
Patch 7 opens the additional ll2 connection for iWARP.
Patches 8-12 contain the algorithm for aligning packets.
