In vxge_hw_vpath_close, __vxge_hw_vp_terminate memsets the vpath which clobbers the spin lock state, then the driver attempts to acquire the spin lock. Resolve this by not zeroing the lock part of vpath struct, clean-up vpath locking in init, close, and fix locking hole in fw_api call.

Hardware time stamp calculation can only be enabled by the privileged function. Enable it always by default and simply use the ethtool interface to set a flag to indicate whether or not the respective function driver should indicate the timestamp along with the received packet. Also, make certain fields in vxge_hw_device_config bit-fields to reduce the size of the struct. Signed-off-by: Jon Mason <jdmason@kudzu.us> Signed-off-by: David S. Miller <davem@davemloft.net>

Most of these are cases where we are trying to read back a register after a write to ensure completion. Simply pre-fixing the readl() or readq() with "(void)" is sufficient because these are volatile operations and the compiler cannot eliminate them just because no real assignment takes place. The case of free_rxd_blk()'s assignments to "struct buffAdd *ba" is a real spurious assignment as this variable is completely otherwise unused. Signed-off-by: David S.

When the RX network flow classification interface was originally defined for reporting and controlling of flow hashing, AH and ESP were not given distinct flow class codes (apparently because the Sun Neptune hardware treats them very similarly). For flow steering, they must be distinguished, so new and separate flow class codes were added for AH and ESP. But for backward- compatibility, flow hash operations should continue to support the original class codes. Signed-off-by: Ben Hutchings <bhutchings@solarflare.com> Signed-off-by: David S.

This code was cribbed from niu, so gfar_set_hash_opts() begins by converting the ethtool flow class code into a class code for Sun Neptune hardware, then does the same thing again for the hardware it's really dealing with. It may also return -1 (-EPERM) for some unhandled ethtool flow class codes. Remove the useless code and definitions, and fix the error code.

This is a stab at replacing old ethtool phys_id with set_phys_id on the Qlogic 10Gb driver. Compile tested only.

This change is meant to add an ntuple data extensions to the rx network flow classification specifiers. The idea is to allow ntuple to be displayed via the network flow classification interface. The first patch had some left over stuff from the original flow extension flags I had added. That bit is removed in this patch. The second had some left over comments that stated we ignored bits in the masks when we actually match them. This work is based on input from Ben Hutchings.

This change is meant to prevent a possible null pointer dereference if NETIF_F_NTUPLE is defined but the set_rx_ntuple function pointer is not. The main motivation behind this patch is to eventually replace the ntuple interfaces entirely with the network flow classifier interfaces. This allows the device drivers to maintain the ntuple check internally while using the network flow classifier interface for setting up and displaying rules.

Machines are getting deadlock in four node cluster environment. All nodes are accessing (find /gfs2 -depth -print|cpio -ocv > /dev/null) 200 GB storage on a GFS2 filesystem. This result in memory fragmentation and driver receives 18 frags for 1448 byte packets. For non tso packet, fw drops the tx request, if it has >14 frags. Fixing it by pulling extra frags.

On some old MAC chips without COE sometime the Transmit Underflow error is issued. The driver aborted all the transmission process and initialized it from scratch. This breaks the network activity as raised by Nachiketa on a SPEAr board. The patch is to fix this rare underflow event. The driver will only clear the interrupt and the Tx DMA will go out the Suspend state as soon as the descriptor is fetched again. The driver will continue to bump-up the DMA FIFO threshold that, indeed, helped somebody to prevent this kind of error in the past as well.

In commit 13583b16 ("PCI: refactor io size calculation code") Ram had a thinko in the refactorization of the code: the end result used the variable 'align' for the bus alignment, but the original code used 'min_align'. Since then, another use of that 'align' variable got introduced by commit c8adf9a3 ("PCI: pre-allocate additional resources to devices only after successful allocation of essential resources.") Fix both of those uses to use 'min_align' as they should.

This also fixes possible race when changing receive checksum state and removes IPV6_CSUM_GEN_HACK as it's always set. BTW, The claim about fake IPV6 checksum looks dubious. If that were true, then there's a problem in networking core and should be fixed there and not in random drivers. BTW#2, there's no MAINTAINERS entry for this driver. I assume this driver is supported by Micrel? Signed-off-by: Michał Mirosław <mirq-linux@rere.qmqm.pl> Signed-off-by: David S. Miller <davem@davemloft.net>

This also removes TSO as it's made fully in software --- better to leave this to networking core. If the MAC features can be detected at probe time and not at open, then stmmac_fix_features could be simplified by limiting hw_features. That's also better for users as they don't see offloads being togglable but never turned on. Redundant fallbacks for TX csum are removed as it's already handled by network core.

The reverse path filter interferes with IPsec subnet-to-subnet tunnels, especially when the link to the IPsec peer is on an interface other than the one hosting the default route. With dynamic routing, where the peer might be reachable through eth0 today and eth1 tomorrow, it's difficult to keep rp_filter enabled unless fake routes to the remote subnets are configured on the interface currently used to reach the peer. IPsec provides a much stronger anti-spoofing policy than rp_filter, so this patch disables the rp_filter for packets with a security path.
