e1000/base: Synchronize PHY interface on non-ME systems. On power up, the MAC - PHY interface needs to be set to PCIe, even if the cable is disconnected. In ME systems, the ME handles this on exit from the Sx (Sticky mode) state. In non-ME, the driver handles it. Added a check for non-ME system to the driver code that handles it.

e1000/base: Increased timeout of reset check. Previously, in check_reset_block RSPCIPHY was polled for 100 ms before determining that the ME veto was set. This was not enough and it was increased to 300 ms.

e1000/base: Disabled IPv6 extension header parsing on 82575. Disabled IPv6 options as per hardware limitation.

e1000/base: Prevent ULP flow if cable connected. Enabling ULP on link down when the cable is connected caused an infinite loop of link up/down indications in the NDIS driver. The driver now enables ULP only when the cable is disconnected.

e1000/base: Support different EEARBC for i210. EEARBC has changed on i210. It means EEARBC has a different address on i210 than on other NICs. So, add a new entity named EEARBC_I210 to the register list and make sure the right one is being used on i210.

e1000/base: Fix K1 configuration. Added fix for the following updates to the K1 configurations: TX idle period for entering K1 should be 128 ns. Minimum TX idle period in K1 should be 256 ns.

e1000/base: Fix link detect flow. Fix link detect flow in case where auto-negotiate is not enabled, by calling e1000_setup_copper_link_generic instead of e1000_phy_setup_autoneg .

e1000/base: Fix link check for i354 M88E1112 PHY. The e1000_check_for_link_media_swap() function is supposed to check PHY page 0 for copper and PHY page 1 for “other” (fiber) links. The driver switched back from page 1 to page 0 too soon, before e1000_check_for_link_82575() is executed and was never finding the link on the fiber (other). If the link is copper, as the M88E1112 page address is set to 1, it should be set back to 0 before checking this link.

e1000/base: Fix beacon duration for i217. Fix for I217 Packet Loss issue - The Management Engine sets the FEXTNVM4 Beacon Duration incorrectly. This fix ensures that the correct value will always be set. Correct value for this field is 8 usec.

e1000/base: Fix TIPG for non 10 half duplex mode. TIPG value is increased when setting speed to 10 half duplex to prevent packet loss. However, it was never decreased again when speed changed. This caused performance issues in the NDIS driver. Fix this to restore TIPG to default value on non 10 half duplex.

e1000/base: Fix reset of DH89XXCC SGMII. For DH89XXCC_SGMII, a write flush leaves registers of this device trashed (0xFFFFFFFF). Add check for this device. Also, after both Port SW Reset and Device Reset case, the platform should wait at least 3ms before reading any registers. Remove this condition since waiting is conditionally executed only for Device Reset.

e1000/base: Fix redundant PHY power down for i210. Bit 11 of PHYREG 0 is used to power down PHY. The use of PHYREG 16 is no longer necessary.

e1000/base: fix jumbo frame CRC failures. Change the value of register 776.20[11:2] for jumbo mode from 0x1A to 0x1F. This is to enlarge the gap between read and write pointers in the TX FIFO.

e1000/base: Fix link flap on 82579. Several customers have reported a link flap issue on 82579. The symptoms are random and intermittent link losses when 82579 is connected to specific switches. the Issue was root caused as an inter-operability problem between the NIC and at least some Broadcom PHYs in the Energy Efficient Ethernet wake mechanism. To fix the issue, we are disabling the Phase Locked Loop shutdown in 100M Low Power Idle. This solution will cause an increase of power in 100M EEE link. It may cost an additional 28mW in this specific mode.

igb: Fixed IEEE1588 frame identification in I210. Fixed issue where the flag PKT_RX_IEEE1588_PTP was not being set in the Intel I210 NIC, as the EtherType in RX descriptor is in bits 8:10 of Packet Type and not in the default bits 0:2.

igb: Fixed VF start with PF stopped. VF needs the PF interrupt support initialized even if not started.

igb: Fixed VF MAC address when using with DPDK PF. Assign a random MAC address in VF when not assigned by PF.

igb: Removed CRC bytes from byte counter statistics.

ixgbe: Fixed issue with X550 DCB. Fixed a DCB issue with x550 where for 8 TCs (Traffic Classes), if a packet with user priority 6 or 7 was injected to the NIC, then the NIC would only put 3 packets into the queue. There was also a similar issue for 4 TCs.

ixgbe: Removed burst size restriction of vector RX. Fixed issue where a burst size less than 32 didn’t receive anything.

ixgbe: Fixed VF start with PF stopped. VF needs the PF interrupt support initialized even if not started.

ixgbe: Fixed TX hang when RS distance exceeds HW limit. Fixed an issue where the TX queue can hang when a lot of highly fragmented packets have to be sent. As part of that fix, tx_rs_thresh for ixgbe PMD is not allowed to be greater then to 32 to comply with HW restrictions.

ixgbe: Fixed rx error statistic counter. Fixed an issue that the rx error counter of ixgbe was not accurate. The mac short packet discard count (mspdc) was added to the counter. Mac local faults and mac remote faults are removed as they do not count packets but errors, and jabber errors were removed as they are already accounted for by the CRC error counter. Finally the XEC (l3 / l4 checksum error) counter was removed due to errata, see commit 256ff05a9cae for details.

ixgbe: Removed CRC bytes from byte counter statistics.

i40e: Fixed base driver allocation when not using first numa node. Fixed i40e issue that occurred when a DPDK application didn’t initialize ports if memory wasn’t available on socket 0.

i40e: Fixed maximum of 64 queues per port. Fixed an issue in i40e where it would not support more than 64 queues per port, even though the hardware actually supports it. The real number of queues may vary, as long as the total number of queues used in PF, VFs, VMDq and FD does not exceeds the hardware maximum.

i40e: Fixed statistics of packets. Added discarding packets on VSI to the stats and rectify the old statistics.

i40e: Fixed issue of not freeing memzone. Fixed an issue of not freeing a memzone in the call to free the memory for adminq DMA.

i40e: Removed CRC bytes from byte counter statistics.

mlx: Fixed driver loading. The mlx drivers were unable to load when built as a shared library, due to a missing symbol in the mempool library.

mlx4: Performance improvements. Fixed bugs in TX and RX flows that improves mlx4 performance.

mlx4: Fixed TX loss after initialization.

mlx4: Fixed scattered TX with too many segments.

mlx4: Fixed memory registration for indirect mbuf data.

vhost: Fixed Qemu shutdown. Fixed issue with libvirt virsh destroy not killing the VM.

virtio: Fixed crash after changing link state. Fixed IO permission in the interrupt handler.
