Improve myri10ge parity error detection and recovery: 1) Don't restore PCI config space to a rebooted NIC until AFTER the host is quiescent. 2) Let myri10ge_close() know the NIC is dead, so it won't waste time waiting for a dead nic to respond to MXGEFW_CMD_ETHERNET_DOWN 3) When the NIC is quiet (link down, or otherwise idle link) use a pci config space read to detect a rebooted NIC. Otherwise we might never notice that a NIC rebooted Signed-off-by:

In general in this file, it is the status field, not the state field, that contains values like OPEN and CLOSED. Indeed, in the first error case, it is the field status that is initialized. I have thus assumed that all of the error handling code should be the same, and moved it to the end of the function to emphasize its commonality. Signed-off-by:

In all rx'd SKB cases, atalk_rcv() either eventually jumps to or falls through to the label out:, which returns numeric 0. Numeric 0 corresponds to NET_RX_SUCCESS, which is incorrect in failed SKB cases. This patch makes atalk_rcv() provide the correct returns by: o explicitly returning NET_RX_SUCCESS in the two success cases o having the out: label return NET_RX_DROP, instead of numeric 0 o making the failed SKB labels and processing more consistent with other _rcv() routines in the kernel, simplifying validation and removing a backwards goto Signed-off-by:Mark Smith <markzzzsmith@yahoo.com.au> Signed-off-by:

Instead of a large (physically) linear buffer, we generate a set of paged sk_buff, so no extra memory copy is involved. This removes high-order allocations and saves quite a bit of memory. Phonet MTU is 65541 bytes, so the two buffers were padded to 128 kilo-bytes each. Now, we create 17 page buffers, almost a 75% memory use reduction. Signed-off-by:

With the current driver, the MTU is purely indicative, so there is no need to synchronize with the receive path. Signed-off-by:

The bank offset was being incorrectly calculated on ICH9 parts with a bank size of 8K (instead of the more common 4K bank) which would cause any NVM writes to be done on the wrong address after switching from bank 1 to bank 0. Additionally, assume we are meant to use bank 0 if a valid bank is not detected, and remove the unnecessary acquisition of the SW/FW/HW semaphore when writing to the shadow ram version of the NVM image.

For ICHx parts, write the EXTCNF_CTRL.SWFLAG bit once when trying to acquire the SW/FW/HW semaphore instead of multiple times to prevent the hardware from having problems (especially for systems with manageability enabled), and extend the timeout for the hardware to set the SWFLAG bit.

For 82599, packet split has to be disabled for FCoE direct data placement. However, this is only required on received queues allocated for FCoE. This patch adds a per ring flags to indicate if packet split is disabled on a per queue basis, particularly for FCoE, as packet split must be disabled for large receive using direct data placement (DDP).

Instead of passing the register index of the corresponding rx_ring and find the way back to get to corresponding rx_ring in ixgbe_configure_srrctl(), simplify the function ixgbe_configure_srrctl() by passing the rx_ring into it. Then the register index for that rx_ring is already available from rx_ring->reg_idx. Signed-off-by:

As it is, parts of the ioctl runs under the RTNL and parts of it do not. The unlocked section is still protected by the BKL, but there can be subtle races. For example, Eric Biederman and Paul Moore observed that if two threads tried to create two tun devices on the same file descriptor, then unexpected results may occur. As there isn't anything in the ioctl that is expected to sleep indefinitely, we can prevent this from occurring by extending the RTNL lock coverage. This also allows to get rid of the BKL. Finally, I changed tun_get_iff to take a tun device in order to avoid calling tun_put which would dead-lock as it also tries to take the RTNL lock. Signed-off-by:

Commit f0b3fbea ("FEC Buffer rework") breaks transmission of packets where the skb data buffer is not memory aligned according to FEC_ALIGNMENT. It incorrectly passes to dma_sync_single() the buffer address directly from the skb, instead of the address calculated for use (which may be the skb address or one of the bounce buffers). It seems there is no use converting the cpu address of the buffer to a physical either, since dma_map_single() expects the cpu address and will return the dma address to use in the descriptor. So remove the use of __pa() on the buffer address as well. This patch is against 2.6.30-rc5. This breakage is a regression over 2.6.30, which does not have this problem. Signed-off-by:
