Add new data structure "vports table" to manage vports caps efficiently. Since the number of vports is much smaller than their IDs, this vports table is implemented as a hash table.

Vports can be added and removed dynamically after adding SF support. Vports numbers are not contiguous in such case. This means that we cannot query all of the ports one by one, dynamic support will query and cache the vport details on demand. Caching is possible since the vport to ICM address mapping is static. This will allow to query a port that was added during runtime, for example with a SF.

The Embedded CPU Physical Function (ECPF) vport, is part of every
eswitch running on an Embedded CPU (EC). In such cases the ECPF vport is
also the eswitch manager port to which all missed traffic is direct.
Ports are queried with the following logic:
For Eswitch:
vport 0 (PF): vport = 0, other = false
vport 1..n: vport = x, other = true
esw_manager = vport 0 (PF)
For Embedded CPU Eswitch:
vport 0 (ECPF): vport = 0, other = false
vport 0 (PF): vport = 0, other = true
vport 1..n: vport = x, other = true
esw_manager = vport 0 (ECPF)

This action will allow to direct traffic to a specific ib_port similar to the vport action. Internally each IB port is represented by a vport and meta data_reg_c0 value and mask. The meta data is used in a similar way as source vport for skipping rules and determining the source of the traffic when using FDB. IB ports are also useful for LAG since in such case we have the vports of both physical ports (local and other).

Expose flex parsers 4-7 provided by misc4 to extend matching ability of flex parsers, now we can match on all flex parsers at the same time. Signed-off-by: Muhammad Sammar <muhammads@nvidia.com> Signed-off-by: Alex Vesker <valex@nvidia.com> Signed-off-by: Yishai Hadas <yishaih@nvidia.com>
