This change simplifies the configuration of MRQC by consolidating the setting of it into one function. As such the register is no longer set in multiple places which should make any future changes easier to work with. In addition we can combine RSS related register writes into the call since enabling all of those bits without enabling RSS itself in MRQC should have no effect. Signed-off-by:

This patch moves the Tx ring configuration into a separate function. In addition the function drops the setting of the head writeback RO bit since head writeback is no longer used within ixgbe. Signed-off-by:

This patch moves the configuration of the MTQC register into it's own function call similar to ixgbe_setup_mrqc. Signed-off-by:

In ixgbe_up_complete we were doing a read-modify-write of TXDCTL followed by another one just a few lines further down. Instead of performing two separate read-modify-writes it would make more sense to combine the two into one. Signed-off-by:

We are unnecessarily modifying the GSO size for all HW when we don't need to. The code can be simplified by moving the check for DCB and the adjustment of the GSO size for 82598 into ixgbe_configure_dcb. Signed-off-by:

This patch removes the redundant DMA alignment code from the Rx buffer allocation path. This code is no longer necessary since all x86 buffers are now DMA aligned due to recent changes to NET_IP_ALIGN and NET_SKB_PAD. It also moves the setting of the Rx queue value into the allocation path since it is more likely that the queue mapping will still be in the cache at the time of allocation. Signed-off-by:

Use integrated net_device_stats instead of a static one, and make sure no transient values are feeded. ndo_get_stats() can be called by concurrent cpus. Signed-off-by:

vxge_get_stats() is racy, since it clears a block of memory (net_stats) possibly still used by other cpus. We can update this driver to full 64bit stats, since ndo_get_stats64() provides a private block to store results, and driver maintains 64bit counters already. We also remove net_stats field from struct vxge_sw_stats Signed-off-by:

struct net_device has its own struct net_device_stats member, so use this one instead of a private copy in the ether1_priv struct. As the new ndo_get_stats function would just return dev->stats we can omit it. This patch also removes an incorrect memset of the stats on open. Signed-off-by:

This patch removes the abstraction introduced by the union skb_shared_tx in the shared skb data. The access of the different union elements at several places led to some confusion about accessing the shared tx_flags e.g. in skb_orphan_try(). http://marc.info/?l=linux-netdev&m=128084897415886&w=2Signed-off-by:Oliver Hartkopp <socketcan@hartkopp.net> Signed-off-by:

The error code is stored in the variable err, but it is the variable ret that is returned instead. So store the error code in ret. Err is then useless.

Use the more descriptive logging message styles. There are whitespace/indentation errors in the original sources that these changes do not modify, so checkpatch errors were cheerfully ignored.

There is no need to check "s". nla_data() doesn't return NULL. Also we already dereferenced "s" at this point so it would have oopsed ealier if it were NULL. Signed-off-by:

These changes may be slightly safer in some instances. There are other kzalloc calls with a multiply, but those calls are typically "small fixed #" * sizeof(some pointer)" and those are not converted. Signed-off-by:

Ensure that TIPC does not re-establish communication with a neighboring node until it has finished updating all data structures containing information about that node to reflect the earlier loss of contact. Previously, it was possible for TIPC to perform its purge of name table entries relating to the node once contact had already been re-established, resulting in the unwanted removal of valid name table entries.

Cause a socket whose TIPC_CONN_TIMEOUT option is zero to wait indefinitely for a response to a connection request using connect(). Previously, specifying a timeout of 0 ms resulted in an immediate timeout, which was inconsistent with the behavior specified by Posix for a socket's receive and send timeout. Signed-off-by:

Modify TIPC's broadcast link so that it counts each piece of a fragmented message individually, rather than as treating the group as a single message. This ensures that proper correlation of sent and received traffic can be done when the broadcast link statistics are displayed, and is consistent with the way fragments are counted by TIPC's unicast links. Signed-off-by:

Allan Stephens authored
Prevent a TIPC node from sending out a LINK_STATE message advertising a broadcast message that it is in the process of sending, but has not yet actually sent. Previously, it was possible for a link timeout to occur in between the time the broadcast link updated its "last message sent" counter and the time the broadcast message was passed to the broadcast bearer for transmission. This ensures that the code which issues the LINK_STATE message isn't informed of the new message until the broadcast bearer has had a chance to send it. Note: The "last message sent" value is stored in the "fsm_msg_count" field of the link structure used by the broadcast link. Since the broadcast link doesn't utilize the normal link FSM, this field can be re-used rather than adding a new field to the broadcast link. Signed-off-by:

Allow TIPC's broadcast link to continue operation when it is unable to send a message to all nodes in the cluster. Previously, the broadcast link attempted to put the broadcast pseudo-bearer into a blocked state; however, this caused a crash because the associated bearer structure is only partially initialized. Further investigation has revealed some conceptual problems with blocking the pseudo-bearer; consequently, this functionality has been disabled for the time being and the undelivered message is eventually resent by the broadcast link's existing message retransmission mechanism (if possible).

Add a check to tipc_recv_msg() to ensure it discards messages arriving on a newly disabled bearer. This is needed to deal with a race condition that can arise if the bearer is in the midst of being disabled when it receives a message. Performing the check after tipc_net_lock has been taken ensures that TIPC's bearers are in a stable state while the message is being processed. Signed-off-by:
