Nithin Nayak Sujir says: ==================== This patch and the following two patches add support for link flap avoidance by maintaining the link on power down. This feature is required for management capable devices to have the management connection uninterrupted on driver reload, reboot and interface up/down. The other pros of this feature are - It speeds up boot up time by several seconds as DHCP addresses can be acquired faster. - It avoids lengthy Spanning Tree delay. On powerup the hardware brings up the phy with default settings. If the link is not up, the management software configures the phy to gigabit and starts autonegotiate. Subsequently, as long as the link is up, the driver and management refrain from resetting and/or changing any configuration that the link depends on. The LNK_FLAP_AVOID setting is an NVRAM user configurable bit and is disabled by default. If this setting is enabled, we skip powering down the phy and resetting it. A second NVRAM setting is 1G_ON_VAUX_OK (off by default). This adds support for gigabit link speed when device is on auxiliary power. ==================== Signed-off-by:

When LFA is enabled, we don't reset the phy. But EEE settings changes don't take effect until the phy is reset. Add a phy reset when we detect a changed EEE setting. Signed-off-by:

Normally on driver load, we set the default settings for speed and flow control. However, if the default setting is not compatible with the current link state, we would autonegotiate and cause a link flap. To avoid this, we pull the current advertised settings into the config. A second scenario is if a user changes the speed/duplex/fc settings when the interface is down. In this case we must not pull the settings from the phy and overwrite user settings. We avoid that by checking the USER_CONFIGURED flag. Signed-off-by:

The current code unnecessarily resets the phy when we use ethtool to change the ring parameters or flow control settings. Remove the phy reset. Signed-off-by:

In tg3_setup_copper_phy(), if autonegotiation is disabled, we need to relink only if the speed or duplex does not match the configured setting. If flow control does not match, a relink is not necessary as flow control is not a PHY setting. Later on, we'll call tg3_setup_flow_ctrl() to set up the MAC to the desired flow control settings if we're in full duplex mode. Signed-off-by:

This patch introduces an UAPI header for the SCTP protocol, so that we can facilitate the maintenance and development of user land applications or libraries, in particular in terms of header synchronization. To not break compatibility, some fragments from lksctp-tools' netinet/sctp.h have been carefully included, while taking care that neither kernel nor user land breaks, so both compile fine with this change (for lksctp-tools I tested with the old netinet/sctp.h header and with a newly adapted one that includes the uapi sctp header). lksctp-tools smoke test run through successfully as well in both cases.

Instead of invalidating all IPv6 addresses with global scope when one decides to use IPv6 tokens, we should only invalidate previous tokens and leave the rest intact until they expire eventually (or are intact forever). For doing this less greedy approach, we're adding a bool at the end of inet6_ifaddr structure instead, for two reasons: i) per-inet6_ifaddr flag space is already used up, making it wider might not be a good idea, since ii) also we do not necessarily need to export this information into user space.

When we set the iftoken in inet6_set_iftoken(), we return -EINVAL when the device does not have flag IF_READY. This is however not necessary and rather an artificial usability barrier, since we simply can set the token despite that, and in case the device is ready, we just send out our rs, otherwise ifup et al. will do this for us anyway.

Since we check for !ipv6_addr_any(&in6_dev->token) in addrconf_prefix_rcv(), make the token initialization on device setup more intuitive by using in6addr_any as an initializer. Suggested-by:

Receiving unhandled notifications is most certainly not an error and should not be logged as one. Knowing that the device sends notifications we don't handle is useful for developers, but there is very little a user can do about this. The message is therefore just annoying noise to most users with devices sending unhandled notifications like e.g. USB_CDC_NOTIFY_RESPONSE_AVAILABLE Cc: Alexey Orishko <alexey.orishko@stericsson.com> Signed-off-by:

This patch adds support for IPv6 tokenized IIDs, that allow for administrators to assign well-known host-part addresses to nodes whilst still obtaining global network prefix from Router Advertisements. It is currently in draft status. The primary target for such support is server platforms where addresses are usually manually configured, rather than using DHCPv6 or SLAAC. By using tokenised identifiers, hosts can still determine their network prefix by use of SLAAC, but more readily be automatically renumbered should their network prefix change. [...] The disadvantage with static addresses is that they are likely to require manual editing should the network prefix in use change. If instead there were a method to only manually configure the static identifier part of the IPv6 address, then the address could be automatically updated when a new prefix was introduced, as described in [RFC4192] for example. In such cases a DNS server might be configured with such a tokenised interface identifier of ::53, and SLAAC would use the token in constructing the interface address, using the advertised prefix. [...] http://tools.ietf.org/html/draft-chown-6man-tokenised-ipv6-identifiers-02 The implementation is partially based on top of Mark K. Thompson's proof of concept. However, it uses the Netlink interface for configuration resp. data retrival, so that it can be easily extended in future. Successfully tested by myself.

recently many new supports have been added in the stmmac driver w/o taking care about where each new field had to be placed inside the private structure for guaranteeing the best cache usage. This is what I wanted in the beginning, so this patch reorganizes all the fields in order to keep adjacent fields for cache effect. I have also tried to optimize them by using pahole. V2: do not abuse with ____cacheline_aligned_in_smp and keep fields that potentially could stay in the same cache-line for better usage in SMP systems. Signed-off-by:

Using DT for mdiobus and ethernet-phy requires to know the PHY address, which is hard to guess if you don't know it. This patch extends of_mdiobus_register to scan mdiobus for PHYs if reg property of the corresponding node is not set. This also allows to have phy nodes in SoC DT files where the reg property can be overwritten in the board file later. To encourage people to finally set the actual phy address, the mdiobus scan is noisier than required. Signed-off-by:

On the MRF24J40, link-layer acknowledgment request and retry must be turned on explicitly for each packet. Turn this on in the hardware based on the FC_ACK_REQ bit being set in the packet. Also, now that failure to receive an ACK will cause the hardware to report failure of transmission, change the log level for this failure to debug level. Signed-off-by:

Hi Greg, I'm unsure if you or Dave should take that one as it's for one a TTY patch but also living under net/. So I'm uncertain and let you decide! Thanks, Mathias -- >8 -- Subject: [PATCH] TTY: ircomm, use GFP_KERNEL in ircomm_open() We're clearly running in non-atomic context as our only call site is able to call wait_event_interruptible().
