linux-next: manual merge of the net tree with the net-current tree
|
|
Hi David,
Today's linux-next merge of the net tree got a conflict in
drivers/net/netxen/netxen_nic_main.c between commits
e424fa9d6a0add1a9b812b07e3607daaa5b9e53d ("netxen: remove netxen
workqueue") and 232e7d68d50c9ac3a55d716e5ae215ecd1e043b9 ("netxen: free
napi resources during detach") from the net-current tree and commits
6598b169b856793f8f9b80a3f3c5a48f5eaf40e3 ("netxen: enable ip addr
hashing"), f17443f4b01659a5c44d5fc6f5c502c39c293959 ("netxen: refactor
net_device setup code") and 7042cd8f148345bfca6c336f009c96a416674f5e
("netxen: support for ethtool set ringparam") from the net tree.
I fixed it up (I hope) (see below) and can carry the fix as necessary.
