This patch touchs most of the enic port profile handling code.
Tried to break it into sub patches without success.
The patch mainly does the following:
- Port profile operations for a SRIOV VF are modified to work
only via its PF
- Changes the port profile static struct in struct enic to a pointer.
This is because a SRIOV PF has to now hold the port profile information
for all its VF's
- Moved address registration for VF's during port profile ASSOCIATE time
- Most changes in port profile handling code are changes related to indexing
into the port profile struct array of a PF for the VF port profile
information

While playing with a new ADSL box at home, I discovered that ECN
blackhole can trigger suboptimal quickack mode on linux : We send one
ACK for each incoming data frame, without any delay and eventual
piggyback.
This is because TCP_ECN_check_ce() considers that if no ECT is seen on a
segment, this is because this segment was a retransmit.
Refine this heuristic and apply it only if we seen ECT in a previous
segment, to detect ECN blackhole at IP level.

Most sky2 hardware only has a single port, although some variations of the
chip support two interfaces. For the single port case, use the standard
Ethernet driver convention of allocating IRQ when device is brought up
rather than at probe time.
Also, change the error handling of dual port cards so that if second
port can not be brought up, then just fail. No point in continuing, since
the failure is most certainly because of out of memory.
The dual port sky2 device has a single irq and a single status ring,
therefore it has a single NAPI object shared by both ports.

If iwl_scan_initiate() fails for any reason,
priv->scan_request and priv->scan_vif are left
dangling. This can lead to a crash later when
iwl_bg_scan_completed() tries to run a pending
scan request.
In practice, this seems to be very rare due to
the STATUS_SCANNING check earlier. That check,
however, is wrong -- it should allow a scan to
be queued when a reset/roc scan is going on.
When a normal scan is already going on, a new
one can't be issued by mac80211, so that code
can be removed completely. I introduced this
bug when adding off-channel support in commit
266af4c745.

In function fec_enet_mii_init(), it uses non-zero pdev->id as part
of the condition to check the second fec instance (fec1). This works
before the driver supports device tree probe. But in case of device
tree probe, pdev->id is -1 which is also non-zero, so the logic becomes
broken when device tree probe gets supported.
The patch change the logic to check "pdev->id > 0" as the part of the
condition for identifying fec1.

FEC can work without a phy reset on some platforms, which means not
very platform necessarily have a phy-reset gpio encoded in device tree.
Even on the platforms that have the gpio, FEC can work without
resetting phy for some cases, e.g. boot loader has done that.
So it makes more sense to have the phy-reset-gpio request failure as
a debug message rather than a warning, and get fec_reset_phy() return
void since the caller does not check the return anyway.
