[PATCH 01/19] net/txgbe: fix to parse tunnel packets

[Jiawen Wu]

The outer-ipv6 tunnel packet was parsed to the wrong packet type, remove
the default RTE_PTYPE_L2_ETHER and RTE_PTYPE_L3_IPV4 flags for tunnel
packets. And correct the calculation of tunnel length for GRE and GENEVE
packets.

Fixes: ca46fcd753b1 ("net/txgbe: support Tx with hardware offload")
Fixes: e5ece1f467aa ("net/txgbe: fix VXLAN-GPE packet checksum")
Fixes: 0e32d6edd479 ("net/txgbe: fix packet type to parse from offload flags")
Fixes: 5bbaf75ed6df ("net/txgbe: fix GRE tunnel packet checksum")

In virtualization mode, target pool should be determined for the

[PATCH 03/19] net/txgbe: fix Tx hang on queue disable

[Jiawen Wu]

The problem of Tx hang also occurs on Wangxun 10Gb NICs, when stop device
under heavy traffic.

refer to commit ac6c5e9af56a ("net/ngbe: fix Tx hang on queue disable")

Disable PCIe bus master to clear BME when stop hardware, and verify there
are no pending requests. Move disabling Tx queue after disabling PCIe bus
master to ensure that there are no packets left to cause Tx hang.

Fixes: b1f596677d8e ("net/txgbe: support device start")

[PATCH 04/19] net/txgbe: restrict the configuration of VLAN strip offload

[Jiawen Wu]

There is a hardware limitation that Rx ring config register is not writable
when Rx ring is enabled, i.e. the TXGBE_RXCFG_ENA bit is set. But disabling
the ring when there is traffic will cause ring get stuck. So restrict the
configuration of VLAN strip offload only if device is started.

[PATCH 05/19] net/txgbe: reconfigure more MAC Rx registers

[Jiawen Wu]

When link status changes, there is a probability that no more packets can
be received on the port, due to hardware defects. These MAC Rx registers
should be reconfigured to fix this problem.

[PATCH 06/19] net/txgbe: fix VF promiscuous and allmulticast

[Jiawen Wu]

The configuration of allmulti and promiscuous modes conflicts
together. For instance, if we enable promiscuous mode, then enable and
disable allmulti, then the promiscuous mode is wrongly disabled.

Fix this behavior by:
- doing nothing when we set/unset allmulti if promiscuous mode is on
- restorting the proper mode (none or allmulti) when we disable
  promiscuous mode

[PATCH 08/19] net/ngbe: keep PHY power down while device probing

[Jiawen Wu]

The internal PHY will be set to default power down after LAN reset,
but the external PHY will not. To keep the PHY behavior consistent,
set PHY power down uniformly here.
