We currently send window update SACKs every time we free up 1 PMTU worth of data. That a lot more SACKs then necessary. Instead, we'll now send back the actuall window every time we send a sack, and do window-update SACKs when a fraction of the receive buffer has been opened. The fraction is controlled with a sysctl.

When sctp_connectx() is used, we pick the first address as primary, even though it may not have worked. This results in excessive retransmits and poor performance. We should select the address that the association was established with. Reported-by:

The "Invalid Stream Identifier" error has a 16 bit reserved field at the end, thus making the parameter length be 8 bytes. We've never supplied that reserved field making wireshark tag the packet as malformed. Reported-by:

This patch implement the sender side for SACK-IMMEDIATELY extension. Section 4.1. Sender Side Considerations Whenever the sender of a DATA chunk can benefit from the corresponding SACK chunk being sent back without delay, the sender MAY set the I-bit in the DATA chunk header. Reasons for setting the I-bit include o The sender is in the SHUTDOWN-PENDING state. o The application requests to set the I-bit of the last DATA chunk of a user message when providing the user message to the SCTP implementation.

This patch implement the receiver side for SACK-IMMEDIATELY extension: Section 4.2. Receiver Side Considerations On reception of an SCTP packet containing a DATA chunk with the I-bit set, the receiver SHOULD NOT delay the sending of the corresponding SACK chunk and SHOULD send it back immediately.

There appears to be a stray setting of the VFE bit when registering vlans. This should not be done as vlan filtering should be enabled any time the interface is not in promiscous mode Signed-off-by:

The Tx unit hang detection code in e1000e detects other hangs caused by hardware components (e.g. Rx, DMA units), but it is not possible to detect exactly which component is hung so it has always assumed a Tx unit hang. When dumping a message to the system log because of a hang, this patch adds more data to help narrow the cause of the issue and makes the message non-Tx-specific. Because this new code reads PHY registers which can sleep, move it off to a workqueue. This and all previously existing work tasks in the driver are now cancelled when the driver is removed.

It was pointed out a pm_qos DMA latency requirement set when the driver is loaded when parts that support early receive of jumbo frames are probed could have that requirement overidden if another part supported by the driver (one that does not support early receive of jumbo frames) is probed later. Change the DMA latency requirement to be per-interface if needed instead of per driver. Signed-off-by:

The driver was only updating MII stats when an LSC up was detected and the interface had not already been reported up to netdev. This meant MII stats returned in response to an SIOCGMIIREG ioctl would always show a link up if it had ever been up. This was misleading the networking daemon guessnet, which uses this ioctl, into making improper network port selections. This fix adds a call to e1000_phy_read_status() to actively read the mii stats before responding to the SIOCGMIIREG ioctl. Signed-off-by:

Copper links with WoL or management enabled (any condition which prevents the phy from being powered down when the interface is taken down) were always reporting link-up when the interface had been taken down. This is because when the interface is taken down (ifconfig ethx down), interrupts are disabled. With no interrupts, there is no LSC interrupt, which is normally required to set "get_link_status", which instructs the driver to query the device for link state. The fix is to force get_link_status to true if the interface is not up. Signed-off-by:
