nfp: offload LAG for tc flower egress

This series from John adds bond offload to the nfp driver.  Patch 5
exposes the hash type for NETDEV_LAG_TX_TYPE_HASH to make sure nfp
hashing matches that of the software LAG.  This may be unnecessarily
conservative, let's see what LAG maintainers think :)

John says:

This patchset sets up the infrastructure and offloads output actions for
when a TC flower rule attempts to egress a packet to a LAG port.

Firstly it adds some of the infrastructure required to the flower app and
to the nfp core. This includes the ability to change the MAC address of a
repr, a function for combining lookup and write to a FW symbol, and the
addition of private data to a repr on a per app basis.

Patch 6 continues by implementing notifiers that track Linux bonds and
communicates to the FW those which enslave reprs, along with the current
state of reprs within the bond.

Patch 7 ensures bonds are synchronised with FW by receiving and acting
upon cmsgs sent to the kernel. These may request that a bond message is
retransmitted when FW can process it, or may request a full sync of the
bonds defined in the kernel.

Patch 8 offloads a flower action when that action requires egressing to a
pre-defined Linux bond.
