gianfar: disable vlan tag insertion by default

2014-11-23T09:55:45+00:00

2.6.x kernels require a similar logic change as commit 51b8cbfc [gianfar: fix bug caused by e1653c3e] introduces for newer kernels. Gianfar driver originally enables vlan tag insertion by default. This will lead to unusable connections on some configurations. Since gianfar nic vlan tag insertion is disabled by default and it is not enabled any longer, it is not necessary to disable it again.

gianfar: disable TX vlan based on kernel 2.6.x

2014-05-19T05:54:24+00:00

2.6.x kernels require a similar logic change as commit e1653c3e [gianfar: do vlan cleanup] and commit 51b8cbfc [gianfar: fix bug caused by e1653c3e] introduces for newer kernels. Since there is something wrong with tx vlan of gianfar nic driver, in kernel(3.1+), tx vlan is disabled. But in kernel 2.6.x, tx vlan is still enabled. Thus,gianfar nic driver can not support vlan packets and non-vlan packets at the same time. Signed-off-by: Zhu Yanjun Signed-off-by: Willy Tarreau

gianfar: Fix crashes on RX path (Was Re: [Bugme-new] [Bug 19692] New: linux-2.6.36-rc5 crash with gianfar ethernet at full line rate traffic)

2010-12-09T21:27:05+00:00

[ Upstream commit 0d1fe1111c667e9c713d7efc7ae468a605f236a4 ] The rx_recycle queue is global per device but can be accesed by many napi handlers at the same time, so it needs full skb_queue primitives (with locking). Otherwise, various crashes caused by broken skbs are possible. This patch resolves, at least partly, bugzilla bug 19692. (Because of some doubts that there could be still something around which is hard to reproduce my proposal is to leave this bug opened for a month.)

net: Fix OF platform drivers coldplug/hotplug when compiled as modules

2009-10-14T21:54:52+00:00

Some OF platform drivers are missing module device tables, so they won't load automatically on boot. This patch fixes the issue by adding proper MODULE_DEVICE_TABLE() macros to the drivers. Signed-off-by: Anton Vorontsov Signed-off-by: David S. Miller

The generic header has the same new #define's, so that works out fine. - drivers/net/tun.c fix conflict between 89f56d1e9 ("tun: reuse struct sock fields") that switched over to using 'tun->socket.sk' instead of the redundantly available (and thus removed) 'tun->sk', and 2b980dbd ("lsm: Add hooks to the TUN driver") which added a new 'tun->sk' use.

gianfar: Fix build.

Reported by Michael Guntsche -------------------- Commit 38bddf04bcfe661fbdab94888c3b72c32f6873b3 gianfar: gfar_remove needs to call unregister_netdev() breaks the build of the gianfar driver because "dev" is undefined in this function. To quickly test rc9 I changed this to priv->ndev but I do not know if this is the correct one. -------------------- Signed-off-by: David S. Miller
