Prev: [PATCH 2.6.35-rc1] net-next: Fix an overflow bug in vmxnet3 Tx descriptor
Next: of: Provide default of_node_to_nid() when CONFIG_NUMA is not set
From: Andrew O. Shadoura on 24 Jul 2010 22:50
This patch adds wrappers for ethtool to get or set wake-on-LAN
setting without re-inserting the kernel module.
