ixgbe(4): Fix build issue when compiling with netmap enabled

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
