2009-08-19ppp_generic: Help GCC see that 'flen' is always initialized.David S. Miller
It's too stupid to see that we always set flen to something before we use it in ppp_mp_explode(): drivers/net/ppp_generic.c: In function 'ppp_push': drivers/net/ppp_generic.c:1314: warning: 'flen' may be used uninitialized in this function drivers/net/ppp_generic.c:1314: note: 'flen' was declared here This started warning after commit a53a8b56827cc429c6d9f861ad558beeb5f6103f ("ppp: fix lost fragments in ppp_mp_explode() (resubmit)") So just put an explicit unconditional initialization there to hush it up.

2009-08-19sky2: no recyclingStephen Hemminger
Recycling turns out to be a bad idea! For most use cases, the packet can not be reused: TCP packets are cloned. Even for the ideal case of forwarding, it hurts performance because of CPU ping/pong. On a multi-core system forwarding of 64 byte packets is worse much worse: recycling = 24% forwarded vs no recycling = 42% forwarded Signed-off-by: Stephen Hemminger <shemminger@vyatta.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2009-08-19sky2: optimize transmit completionStephen Hemminger
Don't reference the list element in hardware transmit ring on transmit completion. The list element is updated by hardware, therefore it causes a cache miss. Do book keeping in software structure.

2009-08-19sky2: dynamic size transmit ringStephen Hemminger
Allocate and size transmit ring based on parameters. Saves excess space and allows configuring larger rings for testing. Signed-off-by: Stephen Hemminger <shemminger@vyatta.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2009-08-19sky2: simplify list element errorStephen Hemminger
The code for list element error (which should only happen on hardware errors) should be cleaner and safer. Gets rid of unused ring_size argument, which makes next patch easier. Signed-off-by: Stephen Hemminger <shemminger@vyatta.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2009-08-19sky2: transmit ring 64 bit conservationStephen Hemminger
This patch saves elements on transmit ring by only updating the upper 64 bit address when it changes. With many workloads skb's are located in same region, so it saves space. Signed-off-by: Stephen Hemminger <shemminger@vyatta.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2009-08-19sky2: use upper/lower 32 bitsStephen Hemminger

2009-08-14sky2: remove restarting workaround flagStephen Hemminger

2009-08-14sky2: fix pause negotiationStephen Hemminger
The sky2 driver combines auto speed negotiation with automatic negotiation of pause parameters; but the ethtool interface expects them to be split. This patch allows autonegotiation to be used for speed, but manually disable flow control. Signed-off-by: Stephen Hemminger <shemminger@vyatta.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2009-08-14sky2: lock less transmit completionStephen Hemminger
Transmit completion can safely run lockless against transmit start. In the normal case, completion is done from NAPI and only looks at elements that are at the tail of the ring. When doing shutdown or reset, the transmiter should be completely block by NAPI disable and blocking of transmit queue. Based on earlier work by Mike McCormack.

2009-08-14sky2: cleanup restart operationsStephen Hemminger
This unifies the places that bounce the device (suspend/resume and restart). And makes the operations have the same semantics as normal dev_open/dev_stop. This also avoids setting the multicast addresses twice when device is brought up. Signed-off-by: Stephen Hemminger <shemminger@vyatta.com> Signed-off-by: David S. Miller <davem@davemloft.net>

2009-08-14sky2: hold spinlock around phy_power_downStephen Hemminger
Avoid any possible problems with accessing PHY registers on shutdown. This is a purely theoretical issue and is not related to any of the outstanding bug reports. Since receiver and transmitter are already shutdown and phy interrupts for this device are already disabled, there should already be enough protection. Suggested by Mike McCormack.

2009-08-14sky2: Reset tx train after interrupts disabled.Mike McCormack
Reseting the tx chain too soon results in invalid tx queue positions being delivered in the status queue.

2009-08-14ath: add common ath_rxbuf_alloc() and make ath9k use itLuis R. Rodriguez
Turns out ath5k and ath9k can share the same helper to allocates RX skbs. We allocate skbs aligned to the cache line size. This requirement seems to have come from AR5210; when this was not done it seems sometimes we'd get bogus data. I'm also told it may have been a performance enhancement consideration. In the end I can't be sure we can remove this on new hardware so just keep this and start sharing it through ath.ko. Make ath9k start using this, ath5k is next. Signed-off-by: Luis R.

2009-08-14ath5k: Use SWI to trigger calibrationNick Kossifidis
* Get rid of calibration timer, instead use a software interrupt to schedule the calibration tasklet. a) We don't need a timer for this, there is no need for accuracy even with round_jiffies i think this is a waste of resources. Also we don't need to run calibration if we are idle (no interrupts). b) When we add ANI support we 'll just extend the poll function and calibration tasklet and handle all periodic phy calibration on one place (much cleaner). c) Having calibration on a tasklet is better since during calibration we can't transmit or receive (antennas are detached to measure noise floor), previously calibration could run in parallel with tx/rx and interfere (packet loss). v2: kill tasklet on stop_hw, stop/wake queues v3: use time_is_before_eq_jiffies to compare timestamp with current time Signed-off-by: Nick Kossifidis <mickflemm@gmail.com> Signed-off-by: John W.
