Sync with FreeBSD's up to r326022, fix bugs and some improvements:
- Don't limit number of queue pair to 8. Take chip's max TX queues and
  max RX queues into account.
- Add C3000 (Denverton) support.
- Add bypass function support for bypass adapters.
- Change EEE sysctl.
- Remove thermal test sysctl.
- ixv(4): set RSS mapping.
- ixv(4): Add TSOv6.
- ixv(4): Fix hardware counter.
- ixv(4): Make TX/RX descriptors size the same as ixg(4).
- ixv(4): Print device name in ixv_attach().
- ixv(4): Make mailbox statistic counters evcnt(9).
- ixv(4): Fix a problem that mailbox interrupt never occurred.
- ixv(4): Don't check neither VTEICR nor VTEICS same as Linux. It
  seems that both registers can't be used to check which MSI-X vector
  is triggered.
- ixv(4): Print Mailbox API version.
- Print driver feature capabilities and enable bits when verbose boot.
- Fix a bug that X550EM_A (Denverton) can't force 10BaseT.
- Remove all half-duplex setting because of the chip specification.
- Add 2.5GBASE-T and 5GBASE-T support.
- Set ifm_baudrate correctly.
- Protect ec_multi* with mutex like other MP safe Ethernet drivers.
- On X550 and newer, print NVM Image Version with %u.%02x.
- On X540, print PHY FW Revision with %u.%x. 0x4030 will be printed
  as "Revision 4.3 ID 0x0"
- Fix value check of OEM_NVM_IMAGE_VER.
- Print PHY ID only for copper PHY.
- Fix a bug that X550 and newer didn't linkup if it forces
  100BaseTX-FDX or 10BaseT-FDX.
- Fix a bug that RX may accesses freed area. It also fixes a problem
  that if_init() takes long time on many core machine.
- Check ETHERCAP_VLAN_HWTAGGING in ixgbe_setup_vlan_hw_support(). This
  change has no influence to netbsd because it's enabled by default
  and NetBSD has no API to disable it.
- Whitespace fix.
