Currently, most drivers do not support transmit SO_TIMESTAMPING. For those that do support it, there is one appropriate response to the get_ts_info query. This patch adds a common function providing this response. Signed-off-by:

This commit adds a new ethtool ioctl that exposes the SO_TIMESTAMPING capabilities of a network interface. In addition, user space programs can use this ioctl to discover the PTP Hardware Clock (PHC) device associated with the interface. Since software receive time stamps are handled by the stack, the generic ethtool code can answer the query correctly in case the MAC or PHY drivers lack special time stamping features. Signed-off-by:

This commit adds a method that MAC drivers may call in order to find out the device number of their associated PTP Hardware Clock. Signed-off-by:

In 72331bc0 [ipv6: Fix RTM_GETROUTE's interpretation of RTA_IIF to be consistent with ipv4] the code of 'inet6_rtm_getroute()' was re-ordered such that the reference to 'rt->dst' is incremented prior skb allocation. Hence, if 'alloc_skb()' fails, must drop a reference from 'rt->dst'. Add the missing 'dst_release()' call. Signed-off-by:

This commit removes the legacy timecompare code from the igb driver and offers a tunable PHC instead. Signed-off-by:

This patch adds a source file implementing a PHC. Only the basic clock operations have been implemented, although the hardware would offer some ancillary functions. The code is fairly self contained and is not yet used in the main igb driver. Every timestamp and clock read operation must consult the overflow counter to form a correct time value. Access to the counter is protected by a spin lock, and the counter is implemented using the standard cyclecounter/timecounter code. Signed-off-by:

This patch modifies ixgbe_get_pcie_msix_count_generic() to support all current HW and removes the 82598 specific function. - change the type of ixgbe_get_pcie_msix_count_generic() to u16 - include a check to make sure the maximum allowed number of vectors is not exceeded. Signed-off-by:

Restore remote-faule detection, which periodically checks for remote-fault on the MAC layer. In case physical link appear to be up but fault is set, it will provide a link down indication, and when the fault is cleared, it will indicate link up again. Signed-off-by:

Until now, the bnx2x driver needed at least 2 available msix interrupt vectors in order to use msix. This patch add the possibility of configuring msix when only one interrupt vector is available. Notice this patch contains lines with over 80 characters, as it keeps print strings in a single line. Signed-off-by:

In the existing code, we only stop queue when the ringbuffer is full, so the current packet has to be dropped or retried from upper layer. This patch stops the tx queue when available ringbuffer is below the low watermark. So the ringbuffer still has small amount of space available for the current packet. This will reduce the overhead of retries on sending. Signed-off-by:

unix_dgram_sendmsg() currently builds linear skbs, and this can stress page allocator with high order page allocations. When memory gets fragmented, this can eventually fail. We can try to use order-2 allocations for skb head (SKB_MAX_ALLOC) plus up to 16 page fragments to lower pressure on buddy allocator. This patch has no effect on messages of less than 16064 bytes. (on 64bit arches with PAGE_SIZE=4096) For bigger messages (from 16065 to 81600 bytes), this patch brings reliability at the expense of performance penalty because of extra pages allocations. netperf -t DG_STREAM -T 0,2 -- -m 16064 -s 200000 ->4086040 Messages / 10s netperf -t DG_STREAM -T 0,2 -- -m 16068 -s 200000 ->3901747 Messages / 10s Signed-off-by:
