fec3608673 mlx4: query netdevice to get initial MAC address
Querying the netdevice instead of deriving the port's MAC address from its
GID is less prone to errors. There is no guarantee that the GID will always
contain it nor that the algorithm won't change.

1c214ab7f0 mlx4: fix support for multiple vlan filters
This commit fixes the "Multiple RX VLAN filters can be configured, but only
the first one works" bug. Since a single flow specification cannot contain
several VLAN definitions, the flows table is extended with MLX4_MAX_VLAN_IDS
possible specifications per configured MAC address.

2d402df262 mlx4: remove provision for flow creation failure in DMFS A0 mode
Starting from MLNX_OFED 3.0 FW 2.34.5000 when working with optimized
steering mode (-7) QPs can be attached to the port's MAC, therefore no need
for the check.

baf036766f mlx4: use MOFED 3.0 extended flow steering API
This commit drops "exp" from related function and type names to stop using

e947d2ec8b mlx4: improve accuracy of link status information
Query interface properties using the ethtool API instead of Verbs
through ibv_query_port(). The returned information is more accurate for
Ethernet links since several link speeds cannot be mapped to Verbs
semantics.

643777a171 mlx4: allow application to partially fork
Although using the PMD from a forked process is still unsupported, this
commit makes Verbs safe enough for applications to call fork() for other
purposes.

d6145abec4 mlx4: fix 32-bit build
Fix warning messages "cast to pointer from integer of different size" when
compiling DPDK in 32 bit with Mellanox PMD.

SGE addresses are 64 bit integers, converting them to pointers must be done
through uintptr_t to avoid compilation warnings when those have a different
size.
