* ucc_geth: Do not bring the whole IF down when TX failure.Joakim Tjernlund2010-11-121-6/+9
| | | | | | | | | | | | | | | ucc_geth_close lacks a cancel_work_sync(&ugeth->timeout_work) to stop any outstanding processing of TX fail.

Without this patch the driver will stop transmiting when TX queue becomes full since 'bd == ugeth->txBd[txQ]' actually checks for two things: queue empty or full.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Since commit 0b9da337dca972e7a4144e298ec3adb8f244d4a4 ("Rework ucc_geth driver to use of_mdio infrastructure") the fixed-link support is broken. This patch fixes the support by removing !ug_info->phy_node check, and adds a call to of_phy_connect_fixed_link() if a phy is not attached to the MAC. Also, remove an old fixed-link code that we don't use any longer.

* | ucc_geth: Add support for skb recyclingAnton Vorontsov2009-07-081-12/+28
| | | | | | | | | | | | | | | | | | | | | | We can reclaim transmitted skbs to use in the receive path, so-called skb recycling support. Also reorder ucc_geth_poll() steps, so that we'll clean tx ring firstly, thus maybe reclaim some skbs for rx. Signed-off-by: Anton Vorontsov <avorontsov@ru.mvista.com> Signed-off-by: David S.

* | net: use NETDEV_TX_OK instead of 0 in ndo_start_xmit() functionsPatrick McHardy2009-07-061-1/+1
|/ | | | | | | | | | | This patch is the result of an automatic spatch transformation to convert all ndo_start_xmit() return values of 0 to NETDEV_TX_OK. Some occurences are missed by the automatic conversion, those will be handled in a seperate patch. Signed-off-by: Patrick McHardy <kaber@trash.net> Signed-off-by: David S.

| | | | | | | | | | | | | | | | | | | | | | | | This reverts commit 047584ce94108012288554a5f84585d792cc7f8f. This patch meshes badly with "net: Rework ucc_geth driver to use of_mdio infrastructure" (0b9da337dca972e7a4144e298ec3adb8f244d4a4). Since most of the patch needs to be reworked, it is clearer to revert the patch and then apply the corrected version Signed-off-by: Grant Likely <grant.likely@secretlab.ca> Signed-off-by: David S.

| | | | | | | | | | | | | | | | | | | | | | | | Inspired by the patch for 8139too (bda6a15a). Currently we can't set mac address on a running ucc_geth device. But this is needed when you use this device as a bonding slave in bonding device in balance-alb mode. So add this feature for ucc_geth device.
