- Add SFP support. Module insertion/removal is not supported yet.
  Currently, SFP detection is only done in the driver's attach phase.
- Detect the Media Auto Sense feature. Not supported yet.
- Fix SFF_SFP_ETH_FLAGS_100FX. It's not 0x10 but 0x20.
- Add extra delay in wm_serdes_power_up_link_82575().
- Add Intel I219 LM10-LM15 and V10-V14.
- wm(4) can use workqueue as deferred Rx/Tx handler.
  Set hw.wm*.txrx_workqueue=1 to use workqueue instead of softint.
  The default value of hw.wm*.txrx_workqueue is 0 which use softint
  as before.
- Unset RSS UDP flags like ixg(4) and other OSes. To handle IP
  fragmented UDP, first packet and second packet should be processed
  in the same Rx queue.
- It's useless to not to set PCI_PMCSR_PME_STS bit when writing because
  the bit is W1C. Instead, always write PCI_PMCSR_PME_STS bit to clear
  in case it's already set.
- Actually writing always the checksum offload context descriptor
  makes the HW do extra processing, avoid doing that if possible.
- Fix a bug that the WMREG_EEARBC_I210 register is incorrectly set if
  the system uses iNVM.
- "wmX: 0" on 82542 is difficult to understand, so don't print it.
- Rename some macros and function.
- KNF. Add comment.
