Sync with the remaining part of FreeBSD r328265 except sfp_reinit stuff:
- Always schedule module intterrupt in ixgbe_config_link() when a device is
  SFP+ based.
- Use not loop index but txr->me in ixv_initialize_{transmit,receive}_units().
  It's required for VMDQ but NetBSD doesn't use it, so it's not a bug in
  NetBSD.
- Simplify ixgbe_bp_wd_set(). No functional change.
- Whitespace.

Sync with FreeBSD r331224 except ixv_if_update_admin_status()'s change:
- Fix length of reading buffer when the command is Read Flash in
  ixgbe_host_interface_command().
- Add missing start_hw() call in ixv_init_locked(). This is not a real bug
  because start_hw just set hw->adapter_stopped to false and anyone refer it.
- Style change.
- Update comment.

Read sc_if_flags after taking core lock. Same as if_wm.c rev. 1.418.
