The mlx5 features for 4.14
1) Software paring from Nos
* Software parsing (SWP) is a feature that can be used to instruct the
device to stop using its internal parser and to parse packets on the
transmit path according to offsets set for each packets.
Through this feature, the device allows the handling of checksum and
LSO by the hardware according to the location of IP and TCP/UDP
headers.
2) Decouple UMR usage from the MR cache from Ilya and fix from Kamal
* Previously, UMR (HW population of translation entries) was used
only for MRs allocated from the MR cache.
This resulted in slow allocations of large MRs,
and also limited ODP (which relies on UMR) only to cached MRs.
This series uses UMR for populating translations of any MR,
regardless of the cache. Consequently, allocation speed of new/large
MRs is improved considerably.
3) Add support for multi underlay QP from Yishai
* Set underlay QPN as part of flow rule when it's applicable.
4) Enhanced multi packet WQE from Bodong
* This feature enables sending multiple various sized packets
using a single WQE, where each data segment in the posted WQE
points to a separate packet.
