This updates the network drivers so that they don't access the
ethtool_cmd::speed field directly, but use ethtool_cmd_speed()
instead.
For most of the drivers, these changes are purely cosmetic and don't
fix any problem, such as for those 1GbE/10GbE drivers that indirectly
call their own ethtool get_settings()/mii_ethtool_gset(). The changes
are meant to enforce code consistency and provide robustness with
future larger throughputs, at the expense of a few CPU cycles for each
ethtool operation.
All drivers compiled with make allyesconfig ion x86_64 have been
updated.

This makes sure the ethtool's set_settings() callback of network
drivers don't ignore the 16 most significant bits when ethtool calls
their set_settings().

For Ethernet mode only,
When we want to register QP as promiscuous, it must be added to all the
existing steering entries and also to the default one.
The promiscuous QP might also be on of "real" QPs,
which means we need to monitor every entry to avoid duplicates and ensure
we close an entry when all it has is promiscuous QPs.

Adding a pool of MSI-X vectors and EQs that can be used explicitly by mlx4_core
customers (mlx4_ib, mlx4_en). The consumers will assign their own names to the
interrupt vectors. Those vectors are not opened at mlx4 device initialization,
opened by demand.
Changed the max number of possible EQs according to the new scheme, no longer relies on
on number of cores.
The new functionality is exposed through mlx4_assign_eq() and mlx4_release_eq().
Customers that do not use the new API will get completion vectors as before.

By default, each device is assumed to be able only handle 64 KB chunks
during DMA. By giving the segment size a larger value, the block layer
will coalesce more S/G entries together for SRP, allowing larger
requests with the same sg_tablesize setting. The block layer is the
only direct user of it, though a few IOMMU drivers reference it as
well for their *_map_sg coalescing code. pci-gart_64 on x86, and a
smattering on on sparc, powerpc, and ia64.
Since other IB protocols could potentially see larger segments with
this, let's check those:
- iSER is fine, because you limit your maximum request size to 512
KB, so we'll never overrun the page vector in struct iser_page_vec
(128 entries currently). It is independent of the DMA segment size,
and handles multi-page segments already.
- IPoIB is fine, as it maps each page individually, and doesn't use
ib_dma_map_sg().
- RDS appears to do the right thing and has no dependencies on DMA
segment size, but I don't claim to have done a complete audit.
- NFSoRDMA and 9p are OK -- they do not use ib_dma_map_sg(), so they
doesn't care about the coalescing.
- Lustre's ko2iblnd does not care about coalescing -- it properly
walks the returned sg list.
This patch ups the value on Mellanox hardware to 1 GB, which matches
reported firmware limits on mlx4.

The newest device firmware stores IB vs. Ethernet protocol in two bits
in members_count field of multicast group table (0: Infiniband, 1:
Ethernet). When changing the QP members count for a multicast group,
it important not to reset this information. When calling multicast
attach first time, the protocol type should be specified. In this
patch we always set it IB, but in the future we will handle Ethernet
too. When looking for a QP, the protocol type shoud be checked too.

This patch allows IBoE traffic to be encapsulated in 802.1Q tagged
VLAN frames. The VLAN tag is encoded in the GID and derived from it
by a simple computation.
The netdev notifier callback is modified to catch VLAN device
addition/removal and the port's GID table is updated to reflect the
change, so that for each netdevice there is an entry in the GID table.
When the port's GID table is exhausted, GID entries will not be added.
Only children of the main interfaces can add to the GID table; if a
VLAN interface is added on another VLAN interface (e.g. "vconfig add
eth2.6 8"), then that interfaces will not add an entry to the GID
table.
