* net: preserve ifreq parameter when calling generic phy_mii_ioctl().Richard Cochran2010-07-191-4/+1
| | | | | | | | | | | | The phy_mii_ioctl() function unnecessarily throws away the original ifreq. We need access to the ifreq in order to support PHYs that can perform hardware time stamping. Two maverick drivers filter the ioctl commands passed to phy_mii_ioctl(). This is unnecessary since phylib will check the command in any case.

| | | | | | | | | | If we were unable to detect a PHY on any of the MDIO bus id we tried instead of bailing out with -ENODEV, assume the MAC is connected to a switch and use MDIO bus 0.

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.

* net: Use queue aware tests throughout.David S. Miller2008-07-181-12/+8
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This effectively "flips the switch" by making the core networking and multiqueue-aware drivers use the new TX multiqueue structures. Non-multiqueue drivers need no changes. The interfaces they use such as netif_stop_queue() degenerate into an operation on TX queue zero. So everything "just works" for them. Code that really wants to do "X" to all TX queues now invokes a routine that does so, such as netif_tx_wake_all_queues(), netif_tx_stop_all_queues(), etc. pktgen and netpoll required a little bit more surgery than the others. In particular the pktgen changes, whilst functional, could be largely improved. The initial check in pktgen_xmit() will sometimes check the wrong queue, which is mostly harmless. The thing to do is probably to invoke fill_packet() earlier. The bulk of the netpoll changes is to make the code operate solely on the TX queue indicated by by the SKB queue mapping. Setting of the SKB queue mapping is entirely confined inside of net/core/dev.c:dev_pick_tx(). If we end up needing any kind of special semantics (drops, for example) it will be implemented here. Finally, we now have a "real_num_tx_queues" which is where the driver indicates how many TX queues are actually active. With IGB changes from Jeff Kirsher. Signed-off-by: David S.

* net drivers: fix platform driver hotplug/coldplugKay Sievers2008-04-251-0/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | Since 43cc71eed1250755986da4c0f9898f9a635cb3bf, the platform modalias is prefixed with "platform:". Add MODULE_ALIAS() to the hotpluggable network platform drivers, to re-enable auto loading. NOTE: didn't change drivers/net/fs_enet/fs_enet-main.c "old binding" support. That looks problematic in the first place (it even uses the ancient "struct device_driver" binding scheme for platform_bus!) and I suspect it will vanish soonish when arch/powerpc rules the world.

* cpmac: convert to new Fixed PHY infrastructureAnton Vorontsov2008-02-061-37/+18
| | | | | | | | | | | | | | | | | | | | | | | | | | This patch converts cpmac to the new Fixed PHY infrastructure, though it doesn't fix all the problems with that driver. I didn't even bother to test this patch to compile, because cpmac driver is broken in several ways: 1. This driver won't compile by itself because lack of its header describing platform data; 2. It assumes that fixed PHYs should be created by the ethernet driver. It is wrong assumption: fixed PHYs creation is platform code authority, driver must blindly accept bus_id and phy_id platform data variables instead. Also, it seem that that driver doesn't have actual in-tree users, so nothing to fix further. The main purpose of that patch is to get rid of the following Kconfig warning: scripts/kconfig/conf -s arch/powerpc/Kconfig drivers/net/Kconfig:1713:warning: 'select' used by config symbol 'CPMAC' refers to undefined symbol 'FIXED_MII_100_FDX' Signed-off-by: Anton Vorontsov <avorontsov@ru.mvista.com> Signed-off-by: Kumar Gala <galak@kernel.crashing.org>
