The scheduling of tasklet and keeping the interrupts enabled makes interrupt reduntant. 20% of the Tx interrupts have nothing left to process or could not process as Tx tasklet was running. Signed-off-by:

This patch removes busy wait in tx/rx cleanup. bnad_cb_tx_cleanup() and bnad_cb_rx_cleanup() functions are called from irq context, and currently they do busy wait for the in-flight transmit or the currently executing napi polling routine to complete. To fix the issue, we create a workqueue to defer tx & rx cleanup processing, an in the tx rx cleanup handler, we will wait respective in flight processing to complete, before freeing the buffers.

Added NFC pause/resume logic. We only do NFC pause/resume if NFC version is greater than 0x143 and it was halted before, otherwise we revert to old NFC halt mechanism. Made changes to avoid clearing off the interrupts during the initial pll initialization. Signed-off-by:

The platform is removed, so there are no users of this driver. Signed-off-by:

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 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:
