2008-12-22net: Remove unused netdev arg from some NAPI interfaces.Neil Horman
When the napi api was changed to separate its 1:1 binding to the net_device struct, the netif_rx_[prep|schedule|complete] api failed to remove the now vestigual net_device structure parameter. This patch cleans up that api by properly removing it.. Signed-off-by: Neil Horman <nhorman@tuxdriver.com> Signed-off-by: David S. Miller <davem@davemloft.net>

2008-11-21r6040: convert to net_device_opsStephen Hemminger
Convert driver to new net_device_ops. Compile tested only. Signed-off-by: Stephen Hemminger <shemminger@vyatta.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2008-11-03drivers/net: Kill now superfluous ->last_rx stores.David S. Miller
The generic packet receive code takes care of setting netdev->last_rx when necessary, for the sake of the bonding ARP monitor. Drivers need not do it any more. Some cases had to be skipped over because the drivers were making use of the ->last_rx value themselves. Signed-off-by: David S. Miller <davem@davemloft.net>
2008-09-24r6040: fix wrong assignment in r6040_free_txbufsFlorian Fainelli
This patch fixes a wrong assignment in r6040_free_txbufs on a receive skb pointer while we should actually do this on the transmit skb pointer. Signed-off-by: Florian Fainelli <florian@openwrt.org> Signed-off-by: Jeff Garzik <jgarzik@redhat.com>
2008-09-24r6040: fix bad usage of udelayFlorian Fainelli
This patch fixes the bad usage of udelay(5000), which in turns is a mdelay(5). It causes compilation for ARM where udelay maximum value is checked. Reported-by: Martin Michlmayr <tbm@cyrius.com> Signed-off-by: Florian Fainelli <florian.fainelli@telecomint.eu> Signed-off-by: Jeff Garzik <jgarzik@redhat.com>

2008-07-22r6040: rework init_one error handlingFlorian Fainelli
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 Fainelli
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 Fainelli
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 Fainelli
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: use definitions for magic values in descriptor statusFlorian Fainelli
Define all the descriptor status the MAC can set. 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 Fainelli
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: call napi_disable when puting down the interface and set lp->dev ↵Florian Fainelli
accordingly. We did not call napi_disabled when putting down the interface which should be done. Finally initialize lp->dev when everything is set. Signed-off-by: Florian Fainelli <florian.fainelli@telecomint.eu> Signed-off-by: Jeff Garzik <jgarzik@redhat.com>
2008-07-22r6040: rework the RX buffers allocation routineFlorian Fainelli
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. Signed-Off-By: Joerg Albert <jal2@gmx.de> Signed-off-by: Florian Fainelli <florian.fainelli@telecomint.eu> Signed-off-by: Jeff Garzik <jgarzik@redhat.com>
2008-07-22r6040: fix scheduling while atomic in r6040_tx_timeoutFlorian Fainelli
Add a helper function which only modifies R6040 MAC registers use it when we timeout, and on adapter initialization. Fix the scheduling while atomic but in the timeout routine due to the reallocation of rx/tx buffers.

2008-07-22r6040: fix null pointer access and tx timeoutsFlorian Fainelli
This patch fixes a null pointer access in r6040_rx due to lp->dev not being initialized. Fix the TX timeouts, TX irq was not re-enabled on RX irq Signed-Off-By: Joerg Albert <jal2@gmx.de> Signed-off-by: Florian Fainelli <florian.fainelli@telecomint.eu> Signed-off-by: Jeff Garzik <jgarzik@redhat.com>
2008-07-22r6040: prefix all functions with r6040Florian Fainelli
Prefix all functions inside the r6040 driver with r6040 to avoid namespace clashing. Signed-off-by: Florian Fainelli <florian.fainelli@telecomint.eu> Signed-off-by: Jeff Garzik <jgarzik@redhat.com>
2008-06-27drivers/net/r6040.c: Eliminate double sizeofJulia Lawall
Taking sizeof the result of sizeof is quite strange and does not seem to be what is wanted here. This was fixed using the following semantic patch.
