ixgbe(4): Fix VF build failure on i386 caused by r315333

SYSCTL_ADD_UQUAD on i386 expects a uint64_t pointer, and not an
unsigned long pointer. So change the data type of the original variable to
u64 (uint64_t) from unsigned long, since the statistics are intended to be
64 bits, anyway.

ixgbe(4): Update to 3.2.11-k

Includes:

1. Support for X553 (Denverton) Ethernet devices.
2. Initialization code refactoring.
3. ixgbe-specific netmap code moved to ixgbe folder
(but not removed from dev/netmap/).
4. VF driver full split. Some cleanup can be had due to redundant code,
but this split goes inline with the refactoring.

NOTE: This is a direct commit to stable/10. Newer branches will receive an
iflib-converted version of ixgbe, with these updates included, instead.

Revert r294061

A number of pieces needed (netmap(4)) etc are missing, i.e. the MFCs
were incomplete.

Revert the changes so they can be redone cleanly again and to unbreak GENERIC,
LINT, etc

r271524,r273541,r282967,r283009,r283364.

Add support for reading i2c SFP/SFP+ data from NIC driver and
presenting most interesting fields via ifconfig -v.
This version supports Intel ixgbe driver only.

Tested on: Cisco,Intel,Mellanox,ModuleTech,Molex transceivers

* Add new net/sff8436.h containing constants used to access
QSFP+ data via i2c inteface. These constants has been taken
from SFF-8436 "QSFP+ 10 Gbs 4X PLUGGABLE TRANSCEIVER" standard
rev 4.8.
* Add support for printing QSFP+ information from 40G NICs
such as Chelsio T5.

Example:
cxl1: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> metric 0 mtu 1500

MFC r279393:

Pad RX copy alignment calculation to avoid illegal memory accesses

The optimization made in r239940 is valid for struct mbuf's current structure
and size in FreeBSD, but hardcodes assumptions about sizes of struct mbuf,
which are unfortunately broken if additional data is added to the beginning of
struct mbuf

X-MFC note (discussed with rwatson):

This change requires the MPKTHSIZE definition, which is only available after
head@r277203 and will not be MFCed as it breaks mbuf(9) KPI.

A direct commit to stable/10 and merges to other branches to add the necessary
definitions to work with the code as-is will be done to facilitate this MFC
