([PATCH v6 00/34] e1000x cleanups (preliminary for IGB))

igb is a family of Intel's gigabit ethernet controllers. This series implements
82576 emulation in particular. You can see the last patch for the documentation.

Note that there is another effort to bring 82576 emulation. This series was
developed independently by Sriram Yagnaraman.

- V8 -> V9:
- Rebased.
- Added patch "net/eth: Introduce EthL4HdrProto". This is not strictly necessary
  yet but I'm still adding it because it will be necessary soon and it touches
  some code common for igb and e1000e.
- Replaced Linux internal types in hw/net/igb_regs.h with standard ones.

V7 -> V8:
- Removed obsolete patch
  "hw/net/net_tx_pkt: Introduce net_tx_pkt_get_eth_hdr" (Cédric Le Goater)

V6 -> V7:
- Reordered statements in igb_receive_internal() so that checksum will be
  calculated only once and it will be more close to e1000e_receive_internal().

V5 -> V6:
- Rebased.
- Renamed "test" to "packet" in tests/qtest/e1000e-test.c.
- Fixed Rx logic so that a Rx pool without enough space won't prevent other
  pools from receiving, based on Sriram Yagnaraman's work.

V4 -> V5:
- Rebased.
- Squashed patches to copy from e1000e code and modify it.
- Listed the implemented features.
- Added a check for interrupts availablity on PF.
- Fixed the declaration of igb_receive_internal(). (Sriram Yagnaraman)

V3 -> V4:
- Rebased.
- Corrected PCIDevice specified for DMA.

V2 -> V3:
- Rebased.
- Fixed PCIDevice reference in hw/net/igbvf.c.
- Fixed TX packet switching when VM loopback is enabled.
- Fixed VMDq enablement check.
- Fixed RX descriptor length parser.
- Fixed the definitions of RQDPC readers.
- Implemented VLAN VM filter.
- Implemented VT_CTL.Def_PL.
- Implemented the combination of VMDq and RSS.
- Noted that igb is tested with Windows HLK.

V1 -> V2:
- Spun off e1000e general improvements to a distinct series.
- Restored vnet_hdr offload as there seems nothing preventing from that.
