2014-05-18net/mlx4_en: Fix uninitialized use of 'port_up' in mlx4_en_set_channels()Christian Engelmayer
Function mlx4_en_set_channels() stops running ports before performing the requested action. In that case local variable 'port_up' is set so that the port is restarted at the end of the function, however, in case the port was not stopped, variable 'port_up' is left uninitialized and the behaviour is undetermined.

This causes packet contents corruption because are we not invoking the cache invalidation routines with the proper length.

Packets need to be at least 64 bytes to enter the switch port logic, including the FCS, otherwise they will be discarded as RUNT packets. With packets having Broadcom tags, the 4-bytes tag is first stripped off the packet, and the packet length is then checked, so we need to make sure that the packet length with FCS is at least 64 bytes.

2014-05-14net/mlx4_en: Protect MAC address modification with the state_lock mutexShani Michaelli
This Patches solves an issue that could raise when modifying the device's MAC. It occurs due to a simultaneous access to priv->mac_hash from two contexts. The buggy scenario described below: Context 1: copy the new mac address to the dev->dev_addr field. Context 2: mlx4_en_do_uc_filter removes prev_mac entry from the mac_hash db since it is not in dev->uc and not equal to dev->dev_addr. Context 1: mlx4_en_do_set_mac() calls mlx4_en_replace_mac() to replace prev_mac with dev_addr but it fails to update the mac_hash db since it no longer contains prev_mac, therefore it returns with an error. The fix is to prevent mlx4_en_do_uc_filter from being executed by both of the context 1 calls described above, This is done by putting them both under the mdev->state_lock lock, it will solve this issue since mlx4_en_do_uc_filter is already protected by the mdev->state_lock.

2014-05-14net/mlx4_en: Fix errors in MAC address changing when port is downShani Michaelli
This patch fix an issue that happen when changing the MAC address when the port is down, described as follows: 1. Set the port down. 2. Change the MAC address - mlx4_en_set_mac() will change dev->dev_addr. 3. Set the port up - will result in mlx4_en_do_uc_filter that will remove the prev_mac entry from the mac_hash db. 4. Changing the MAC address again will eventually trigger the call to mlx4_en_replace_mac() in order to replace prev_mac with dev_addr but the prev_mac entry is already not exist in the mac_hash db therefore the operation fails. The fix is to set the prev_mac with the new MAC address so in step 3 above, after setting the port up mlx4_en_get_qp() is updating the mac_hash with the entry of dev_addr which is equal to prev_mac. Therefore in step 4, when calling mlx4_en_replace_mac, the entry related to prev_mac exist in mac_hash and the replace operation succeed.

During heavy traffic, napi is constatntly polling the complition queue and no interrupt is fired. Because of that, changes to irq affinity are ignored until traffic is stopped and resumed. By registering to the irq notifier mechanism, and forcing interrupt when affinity is changed, irq affinity changes will be immediatly enforced.

2014-05-13tg3: Prevent page allocation failure during TSO workaroundMichael Chan
If any TSO fragment hits hardware bug conditions (e.g. 4G boundary), the driver will workaround by calling skb_copy() to copy to a linear SKB. Users have reported page allocation failures as the TSO packet can be up to 64K. Copying such a large packet is also very inefficient. We fix this by using existing tg3_tso_bug() to transmit the packet using GSO.

tg3 uses GSO as workaround if the hardware cannot perform TSO on certain packets. We should not modify the ip header fields if we do GSO on the packet. It happens to work by accident because GSO recalculates the IP checksum and IP total length. Also fix the tg3_start_xmit comment to reflect that this is the only xmit function for all devices.

This reverts commit f8d56d8f892be43a2404356073e16401eb5a42e6 ("net: eth: cpsw: Correctly attach to GPIO bitbang MDIO driver"). Fix potential null-pointer dereference at probe if the mdio-gpio device has not been successfully probed yet. The offending commit is plain wrong for a number of reasons. First of all it accesses internal driver data of an unrelated device. Neither does it check that the data is non-null (which it is in case the device has not been probed yet). Furthermore, the decision on whether to treat any driver data according to the mdio-gpio driver's internals is made based on the node name. But the name is not compared against "mdio" which is the normal name for the node, but rather against "gpio" which the node does not have to be named (and shouldn't be according to the binding documentation).
