2011-09-19ath6kl: Fix static WEP configuration in AP modeJouni Malinen
Configuration of the WEP keys needs to be delayed until the AP mode has been properly started at the target. Partial support for delaying the WEP key configuration was already in place in the driver, but the actual part of deciding when to do this was missing.

2011-09-17bna: Eliminate Small Race Condition Window in RX PathRasesh Mody
Change details: - In a continuous sequence of ifconfig up/down operations, there is a small window of race between bnad_set_rx_mode() and bnad_cleanup_rx() while the former tries to access rx_info->rx & the latter sets it to NULL. This race could lead to bna_rx_mode_set() being called with a NULL (rx_info->rx) pointer and a crash. - Hold bnad->bna_lock while setting / unsetting rx_info->rx in bnad_setup_rx() & bnad_cleanup_rx(), thereby eliminating the race described above.

2011-09-16ixgbe: Make better use of memory allocations in one-buffer mode w/ RSCAlexander Duyck
This patch improves the memory utilization with RSC when in one-buffer mode. This is accomplished by making the default buffer sizes match up with the standard memory allocation sizes minus 1K for shared info and padding overhead. By doing this CPU utilization when doing large receives can be reduced by as much as 8%.

2011-09-16ethtool: Update ethtool_rxnfc::rule_cnt on return from ETHTOOL_GRXCLSRLALLBen Hutchings
A user-space process must use ETHTOOL_GRXCLSRLCNT to find the number of classification rules, then allocate a buffer of the right size, then use ETHTOOL_GRXCLSRLALL to fill the buffer. If some other process inserts or deletes a rule between those two operations, the user buffer might turn out to be the wrong size. If it's too small, the return value will be -EMSGSIZE. But if it's too large, there is no indication of this. Fix this by updating the rule_cnt field on return. Signed-off-by: Ben Hutchings <bhutchings@solarflare.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2011-09-16ethtool: Clean up definitions of rule location arrays in RX NFCBen Hutchings
Correct the description of ethtool_rxnfc::rule_locs; it is an array of currently used locations, not all possible valid locations. Add note that drivers must not use ethtool_rxnfc::rule_locs. The rule_locs argument to ethtool_ops::get_rxnfc is either NULL or a pointer to an array of u32, so change the parameter type accordingly.

2011-09-16sfc: Use correct fields of struct ethtool_coalesceBen Hutchings
An earlier developer misunderstood the meaning of the 'irq' fields and the driver did not support the standard fields. To avoid invalidating existing user documentation, we report and accept changes through either the standard or 'irq' fields. If both are changed at the same time, we prefer the standard field. Also explain why we don't currently use the 'max_frames' fields. Signed-off-by: Ben Hutchings <bhutchings@solarflare.com> Signed-off-by: David S. Miller <davem@davemloft.net>

2011-09-16sfc: Correct reporting and validation of TX interrupt coalescingBen Hutchings
The reported TX IRQ moderation is generated in a completely crazy way. Make it simple and correct. When channels are shared between RX and TX, TX IRQ moderation must be the same as RX IRQ moderation, but must be specified as 0! Allow it to be either specified as the same, or left at its previous value in which case it will be quietly overridden.
