2008-07-23e1000e: fix e1000_netpoll(), remove extraneous e1000_clean_tx_irq() callIngo Molnar1-2/+0
Evgeniy Polyakov noticed that drivers/net/e1000e/netdev.c:e1000_netpoll() was calling e1000_clean_tx_irq() without taking the TX lock. David Miller suggested to remove the call altogether: since in this callpah there's periodic calls to ->poll() anyway which will do e1000_clean_tx_irq() and will garbage-collect any finished TX ring descriptors. This fix solved the e1000e+netconsole crashes i've been seeing: ============================================================================= BUG skbuff_head_cache: Poison overwritten ----------------------------------------------------------------------------- INFO: 0xf658ae9c-0xf658ae9c.

Stephen Rothwell points out that this file got deleted (on purpose) by commit 640c1bce86d1e11ee6a1263fdf6170d3210b1684 ("USB: delete airprime driver"), but then almost immediately incorrectly resurrected by commit 95da310e66ee8090119596c70ca8432e57f9a97f ("usb_serial: API all change"). Delete it again. If it comes back, we'll need to drive a stake through its heart.

2008-07-22r6040: rework init_one error handlingFlorian Fainelli1-19/+25
This patch reworks the error handling in r6040_init_one in order not to leak resources and correcly unmap and release PCI regions of the MAC. Also prefix printk's with the driver name for clarity. Signed-off-by: Florian Fainelli <florian.fainelli@telecomint.eu> Signed-off-by: Jeff Garzik <jgarzik@redhat.com>
2008-07-22r6040: bump release number to 0.18Florian Fainelli1-2/+2
This patch bumps the release of the r6040 driver. There has been quite some versions of it out there, but this one is the one people should report bugs against. Signed-off-by: Florian Fainelli <florian.fainelli@telecomint.eu> Signed-off-by: Jeff Garzik <jgarzik@redhat.com>
2008-07-22r6040: handle RX fifo full and no descriptor interruptsFlorian Fainelli1-7/+15
This patch allows the MAC to handle the RX FIFO full and no descriptor available interrupts. While we are at it replace the TX interrupt with its corresponding definition. Signed-off-by: Florian Fainelli <florian.fainelli@telecomint.eu> Signed-off-by: Jeff Garzik <jgarzik@redhat.com>
2008-07-22r6040: change the default waiting timeFlorian Fainelli1-2/+2
This patch changes the default waiting time of a packet, which along with our previous r6040_rx path, was causing huge delays with another host (160 to 230 ms). Signed-off-by: Florian Fainelli <florian.fainelli@telecomint.eu> Signed-off-by: Jeff Garzik <jgarzik@redhat.com>

2008-07-22r6040: completely rework the RX pathFlorian Fainelli1-82/+62
This patch completely reworks the RX path in order to be more accurate about what is going on with the MAC. We no longer read the error from the MLSR register instead read the descriptor status register which reflects, the error per descriptor. We now allocate skbs on the fly in r6040_rx, and we handle allocation failure instead of simply dropping the packet. Remove the rx_free_desc counter of r6040_private structure since we allocate skbs in the RX path. r6040_rx_buf_alloc is now removed and becomes unuseless.

2008-07-22r6040: rework the RX buffers allocation routineFlorian Fainelli1-9/+44
Rework the RX buffers allocation function so that we do not leak memory in the case we could not allocate skbs for the RX path. Propagate the errors to the r6040_up function where we call the RX buffers allocation function. Also rename the r6040_alloc_txbufs function to r6040_init_txbufs, to reflect what it really does.

2008-07-22sfc: Create one RX queue and interrupt per CPU package by defaultBen Hutchings1-1/+18
Using multiple cores in the same package to handle received traffic does not appear to provide a performance benefit. Therefore use CPU topology information to count CPU packages and use that as the default number of RX queues and interrupts. We rely on interrupt balancing to spread the interrupts across packages.

2008-07-22netdev: bunch of drivers: avoid WARN at net/core/dev.c:1328Anton Vorontsov8-25/+5
The drivers were touching net queue before it has been started, so without this patch, the drivers will potentially WARN at net/core/dev.c:1328. I don't have the hardware for the drivers below, so this patch is untested, and thus should be carefully peer reviewed. tc35815.c au1000_eth.c bfin_mac.c macb.c ^ The four drivers are using phylib, they're calling netif_start_queue() in open() callback. So trivially remove netif_tx_schedule_all(). Phylib will handle netif_carrier_*(). cpmac.c fec_mpc52xx.c fs_enet/fs_enet-main.c sh_eth.c ^ The same as above, but these were also needlessly calling netif_carrier_*() functions. So removed queue calls and also remove carrier calls, since phylib will handle it. fs_enet-main.c also didn't call netif_start_queue() at open(), this is fixed now.
