2006-05-15The ixp2000 driver for the enp2611 was developed on a board withLennert Buytenhek
three gigabit ports, but some enp2611 models only have two ports (and only one onboard PM3386.) The current driver assumes there are always three ports and so it doesn't work on the two-port version of the board at all. This patch adds a bit of logic to the enp2611 driver to limit the number of ports to 2 if the second PM3386 isn't detected.

2006-03-29[PATCH] ixp2000: fix gcc4 breakageLennert Buytenhek
gcc4 doesn't like us declaring a static function inside another function. We can do away with this construct altogether and use BUILD_BUG_ON() instead (idea from Andi Kleen.) Signed-off-by: Lennert Buytenhek <buytenh@wantstofly.org> Signed-off-by: Jeff Garzik <jeff@garzik.org>

2005-12-01[PATCH] enp2611: disable/enable SERDES carrier on interface down/upLennert Buytenhek
Disable/enable the SERDES carrier when an interface is administratively downed/upped. Signed-off-by: Lennert Buytenhek <buytenh@wantstofly.org> Signed-off-by: Jeff Garzik <jgarzik@pobox.com>
2005-12-01[PATCH] pm3386: implement resetLennert Buytenhek
Implement pm3386 reset. A reset zeroes out the internally stored MAC addresses, so we need to save and reload them by hand. Signed-off-by: Lennert Buytenhek <buytenh@wantstofly.org> Signed-off-by: Jeff Garzik <jgarzik@pobox.com>
2005-12-01[PATCH] pm3386: add hook for setting carrierLennert Buytenhek
Add a pm3386 hook for disabling/enabling the SERDES carrier, so that we can disable it when the interface is administratively downed, and enable it when it is upped. Signed-off-by: Lennert Buytenhek <buytenh@wantstofly.org> Signed-off-by: Jeff Garzik <jgarzik@pobox.com>
2005-12-01[PATCH] pm3386: add hook for setting MAC addressLennert Buytenhek
When we reset the pm3386, it loses its internally stored MAC addresses that were programmed into it by the bootloader (and are used by the hardware for the generation of PAUSE frames.) Add a hook to allow setting these addresses so that we can program them back by hand. Signed-off-by: Lennert Buytenhek <buytenh@wantstofly.org> Signed-off-by: Jeff Garzik <jgarzik@pobox.com>

2005-12-01[PATCH] enp2611: use 'dev' in link status timerLennert Buytenhek
We assign nds[i] to a local variable 'dev', which we never use afterwards. Use the local variable instead. Signed-off-by: Lennert Buytenhek <buytenh@wantstofly.org> Signed-off-by: Jeff Garzik <jgarzik@pobox.com>
2005-12-01[PATCH] enp2611: don't check netif_running() in link status timerLennert Buytenhek
Even after an interface has gone !netif_running(), we still want to catch the 'carrier went down' event for our internal bookkeeping. Signed-off-by: Lennert Buytenhek <buytenh@wantstofly.org> Signed-off-by: Jeff Garzik <jgarzik@pobox.com>
2005-12-01[PATCH] ixp2000: use netif_rx_schedule_testLennert Buytenhek
The sky2 driver introduced netif_rx_schedule_test(). This is exactly what we need, so remove our local version of this function (which was called netif_rx_schedule_prep_notup) and use the generic one instead.

2005-11-18[PATCH] intel ixp2000 network driverLennert Buytenhek
The way the hardware and firmware work is that there is one shared RX queue and IRQ for a number of different network interfaces. Due to this, we would like to process received packets for every interface in the same NAPI poll handler, so we need a pseudo-device to schedule polling on. What the driver currently does is that it always schedules polling for the first network interface in the list, and processes packets for every interface in the poll handler for that first interface -- however, this scheme breaks down if the first network interface happens to not be up, since netif_rx_schedule_prep() checks netif_running(). sky2 apparently has the same issue, and Stephen Hemminger suggested a way to work around this: create a variant of netif_rx_schedule_prep() that does not check netif_running(). I implemented this locally and called it netif_rx_schedule_prep_notup(), and it seems to work well, but it's something that probably not everyone would be happy with. The ixp2000 is an ARM CPU with a high-speed network interface in the CPU itself (full duplex 4Gb/s or 10Gb/s depending on the IXP model.) The CPU package also contains 8 or 16 (again depending on the IXP model) 'microengines', which are somewhat primitive but very fast and efficient processor cores which can be used to offload various things from the main CPU. This driver makes the high-speed network interface in the CPU visible and usable as a regular linux network device. Currently, it only supports the Radisys ENP2611 IXP board, but adding support for other board types should be fairly easy.
