2009-07-22fs_enet: Revive fixed link supportAnton Vorontsov1-10/+10
Since commit aa73832c5a80d6c52c69b18af858d88fa595dd3c ("Rework fs_enet driver to use of_mdio infrastructure") the fixed-link support is broken in the fs_enet driver. This patch fixes the support by removing a check for phy_node, and adding a call to of_phy_connect_fixed_link(). Also set netdev parent device via SET_NETDEV_DEV() call, this is needed so that OF MDIO core could find a node pointer for a device. Plus, fix "if (IS_ERR(phydev))" check, in case of errors, of_phy_connect() returns NULL, not ERR_PTR as phy_connect().

2008-07-23netdev: bunch of drivers: avoid WARN at net/core/dev.c:1328Anton Vorontsov1-5/+2
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.

2007-10-18fs_enet: Update for API changesScott Wood2-12/+17
This driver was recently broken by several changes for which this driver was not (or was improperly) updated: 1. SET_MODULE_OWNER() was removed. 2. netif_napi_add() was only being called when building with the old CPM binding. 3. The received/budget test was backwards. 4. to_net_dev() was wrong -- the device struct embedded in the net_device struct is not the same as the of_platform device in the private struct. 5. napi_disable/napi_enable was being called even when napi was not being used.

The old, non-CONFIG_PPC_CPM_NEW_BINDING code can go away once CPM platforms are dropped from arch/ppc (which will hopefully be soon), and existing arch/powerpc boards that I wasn't able to test on for this patchset get converted (which should be even sooner).
