However, we really should check that it is within the skb head as that's the only bit we can modify without copying.

As all current versions of virtio_net generate a value for the header length that's too small, we should optimise this so that we don't copy it twice. This can be done by ensuring that it is at least as large as the place where we'll write the checksum. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au> Signed-off-by: David S.

Through a bug in the tun driver, I noticed that virtio_net is producing bogus hdr_len values. In particular, it only includes the IP header in the linear area, and excludes the entire TCP header. This causes the TCP header to be copied twice for each packet. (The bug omitted the second copy :) This patch corrects this.

Fixes an initialization error; the chip negotiates gigabit, but the driver mistakenly handled it as 100Mb. Changes based on both SiS own GPL driver and forcedeth.

Some firmware mailbox commands require the firmware to communicate with the FCoE driver running on another PCI function. This can potentially take several seconds.

There are 8 banks of 'sub-registers' each of which are accessed through address/data register pair. An example would be reading flash or the xgmac. Accessing these require the driver to wait for a ready bit before writing the address and then accessing the data. This patch increases the timeout to 100us to prevent timeouts that have been seen on some platforms. These register are accessed in process context only.

Each firmware mailbox command can have a different number of valid data elements. When waiting for a mailbox command to complete it the process passes it's element count and waits for the completion. It is possible that while waiting an unrelated firmware async event (AE) can arrive. When this happens, the handler will over write the element count with the value for the newly arrived AE. This can cause the mailbox command to not get all of it's data. This patch restores original mailbox count at the end of the handler.

82599 has a FW running that helps manage the internal SFI PHY. There are also a number of pre-production samples of these SFI-based devices in the field. This patch adds a check to look for the firmware running on all SFP+ based adapters, and displays a warning to the system log if a pre-production adapter is identified. The driver will continue loading though, with no functional degradation. Also remove an old function prototype from ixgbe_82599.c that isn't being used.

This patch adds the functions for ixgbe to initialize Flow Director. It also has the function APIs to add Flow Director filters from the base driver. This also includes ATR, Application Targeted Routing, which is a feature set of Flow Director. This is the hash-based mechanism to automatically identify flows and add filters based on the hash, and direct the Rx of that flow back to that same CPU.

This patch moves the tx cleanup processing out of the MSI-X interrupt processing and gives it it's own napi routine. This allows the driver to process TX cleanup in a polling context instead of in an interrupt context which prevents TX from starving RX.

The v_idx value was being used as both a bitmask and an index. This change makes it so that the q_vector contains the index and allows for much of the code to be simplified since disabling a q_vector involves only clearing one bit in the interrupt bitmask.

This patch changes the driver so that it uses rx_buffer_info->dma to determine if it needs to unmap the page instead of sh_info->nr_frags. This helps to prevent a cache line miss when receiving small packets as the rx_buffer_info data should already be in the cache.

82599 supports multispeed fiber optical modules (10Gbps/1Gbps). Some scenarios can cause the autotry mechanism to not negotiate link properly. What needs to happen is the driver must flap the Tx laser to induce an Rx Loss of Signal on the link partner. This will restart the autotry mechanism to get link into a known state. The software definable pin (SDP) 3 on the 0x10fb NIC is wired to cause a Tx LOS event, which triggers the Rx LOS we require.

When reprogramming the 82599 analog PHY to either SFI optical or Direct Attach Twinax, we need to restart the DSP in the PHY. The current method can cause contention with our FW which is managing PHY state, and will cause unexpected link flaps. This patch fixes the DSP restart by issuing an AN_RESTART in the MAC, which will properly propagate the DSP restart to the PHY. This ensures we don't collide with the FW.
