All of the DESC_ADV macros are currently needing the pointers to be de-referenced before accessing the ring. Instead of having to add all of the asterisks it is easier to just update the macro to expect a pointer to the ring. Signed-off-by:

The Rx init is currently split over ixgbe_configure, ixgbe_configure_rx, and ixgbe_up_complete. Instead of leaving it split over 3 function it is easier to consolidate them all into ixgbe_configure_rx. Signed-off-by:

The Tx init was spread out over ixgbe_configure, ixgbe_configure_tx, and ixgbe_up_complete. This change combines all of that into the ixgbe_configure_tx function in order to simplify the Tx init path. Signed-off-by:

This change moves all GPIE register configuration into a single function. The advantage of this is that we can avoid a number of unnecessary read/modify/write cycles on the register. Signed-off-by:

This change moves the configuration that was done in configure_rx into a separate virtualization configuration function. Signed-off-by:

This change moves all of the Rx DMA control register writes to one central location. This should help to avoid accidentally overwriting existing settings. Signed-off-by:

This change consolidates all of the Rx max frame size and Rx buffer length configuration into a single function. Signed-off-by:

The vmolr is configured already in ixgbe_set_rx_mode for the PF so there is no need to set it again in ixgbe_configure_rx. Instead of using the variable name reg, it is easier to just rename it to gcr_ext to reflect the register contents that the variable holds. Signed-off-by:

Bump the header size for packet split to 512 bytes since this makes the best use of the 1k buffer that is allocated for any skb 512 bytes or smaller. Signed-off-by:

We are accessing the FCTRL register in multiple spots in the init path and we can simplify things by combining the configuration all into ixgbe_set_rx_mode. Signed-off-by:
-
Alexander Duyck authored
The configuration of PSRTYPE was being done conditionally on if packet split is enabled or not. It can be configured always since it will not have any effect when packet split is not enabled. Signed-off-by:

These changes add ixgbe_configure_rx_ring which is used to setup the base function pointers for the ring. Signed-off-by:

Alexander Duyck authored
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:

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

Alexander Duyck authored
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:
