The ixgbe driver was setting up 82598 hardware correctly, so that when promiscuous mode was enabled hardware stripping was turned off. But on 82599 the logic to disable/enable hardware stripping is different, and the code was not updated correctly when the hardware vlan stripping was enabled as default. This change comprises the creation of two new helper functions and calling them from the right locations to disable and enable hardware stripping of vlan tags at appropriate times.

The following situation was observed in the field: tap1 sends packets, tap2 does not consume them, as a result tap1 can not be closed. This happens because tun/tap devices can hang on to skbs undefinitely. As noted by Herbert, possible solutions include a timeout followed by a copy/change of ownership of the skb, or always copying/changing ownership if we're going into a hostile device. This patch implements the second approach. Note: one issue still remaining is that since skbs keep reference to tun socket and tun socket has a reference to tun device, we won't flush backlog, instead simply waiting for all skbs to get transmitted. At least this is not user-triggerable, and this was not reported in practice, my assumption is other devices besides tap complete an skb within finite time after it has been queued. A possible solution for the second issue would not to have socket reference the device, instead, implement dev->destructor for tun, and wait for all skbs to complete there, but this needs some thought, probably too risky for 2.6.34.

bcm_enet_hw_preinit will correctly set values in ENET_CTL_REG for internal or external MII operations, however, bcm_enet_open will blindly overwrite the ENET_CTL_REG register value and thus we will loose any changes to it that were made in bcm_enet_hw_preinit, rendering external MII operations non-working. This would lead to the driver not being able to check for link availability on external PHY setups, and thus we would never get to sending packets because link was down from the driver side. This was completely un-noticed because all boards out there but BCM6338-based ones use internal phy on their enet0 interface.

The tg3 driver is written so that VLAN tagged packets can be accepted, even if CONFIG_VLAN_8021Q or CONFIG_VLAN_8021Q_MODULE is not defined. (Think raw interfaces.) If the device has ASF support enabled, the firmware requires the driver to enable VLAN tag stripping. If VLAN tagging is not explicitly supported by the kernel and ASF is enabled, the driver will have to reinject the VLAN tag back into the packet stream.

On a PCIX bus, the 5701 has a bug which requires the driver to double copy all rx packets. The rx code uses the rx_offset device member as a flag to determine if this workaround should take effect. The following patch will modify the rx_offset member such that this test will become less clear. The patch starts by integrating the workaround check into the packet length check. It rounds out the implementation by relaxing the workaround restrictions if the platform has efficient unaligned accesses.

If a packet has the skb_shared_tx->hardware flag set the device is instructed to generate a TX timestamp and write it back to memory after the frame is transmitted. During the clean_tx_ring operation the timestamp will be extracted and copied into the skb_shared_hwtstamps struct of the skb. TX timestamping is enabled by setting the tx_type to something else than HWTSTAMP_TX_OFF with the SIOCSHWTSTAMP ioctl command. It is only supported by eTSEC devices.
