The hardware supports the MTU to be changed and the driver it self is somewhat prepared to support this. This patch hooks up the callbacks to be able to change the MTU from user-space.

Saeed Mahameed says: ==================== mlx5-updates-2017-06-11 This series provides updates to mlx5 header rewrite feature, from Or Gerlitz. and three more small updates From maor and eran. ------- Or says: Packets belonging to flows which are different by matching may still need to go through the same header re-writes (e.g set the current routing hop MACs and issue TTL decrement). To minimize the number of modify header IDs, we add a cache for header re-write IDs which is keyed by the binary chain of modify header actions. The caching is supported for both eswitch and NIC use-cases, where the actual conversion of the code to use caching comes in separate patches, one per use-case. Using a per field mask field, the TC pedit action supports modifying partial fields. The last patch enables offloading that. ------- From Maor, update flow table commands layout to the latest HW spec. From Eran, ethtool connector type reporting updates. ==================== Signed-off-by: NDavid S. Miller <davem@davemloft.net>

CPSW driver supports PTP v1 messages, but for unknown reasons this filter is not advertised. As result, ./tools/testing/selftests/networking/timestamping/timestamping utility can't be used for testing of CPSW RX timestamping with option SOF_TIMESTAMPING_RX_HARDWARE, because it uses HWTSTAMP_FILTER_PTP_V1_L4_SYNC filter.

Yuval Mintz says: ==================== qed*: Light L2 updates This series does a major overhaul of the LL2 logic in qed. The single biggest change done here is in #5 where we're changing the API qed provides for LL2 [both internally in case of storage and externally in case of RoCE] to become callback-based to allow cleaner scalability in preperation to the future iWARP submission which would aadd additional flavors of LL2. It's also the only patch in series to modify !qed logic [qedr]. Patches prior to that mostly deal with refactoring LL2 code, encapsulating varaious parameters into structure and re-ordering of LL2 code. The latter patches add some small missing bits of LL2 ffunctionality. ==================== Signed-off-by: NDavid S. Miller <davem@davemloft.net>

LL2 today is interrupt driven - when tx/rx completion arrives [or any other indication], qed needs to operate on the connection and pass the information to the protocol-driver [or internal qed consumer]. Since we have several flavors of ll2 employeed by the driver, each handler needs to do an if-else to determine the right functionality to use based on the connection type. In order to make things more scalable [given that we're going to add additional types of ll2 flavors] move the infrastrucutre into using a callback-based approach - the callbacks would be provided as part of the connection's initialization parameters.
