2011-07-17net: vlan, qlcnic: make vlan_find_dev privateDavid Lamparter1-1/+6
there is only one user of vlan_find_dev outside of the actual vlan code: qlcnic uses it to iterate over some VLANs it knows. let's just make vlan_find_dev private to the VLAN code and have the iteration in qlcnic be a bit more direct. (a few rcu dereferences less too) Signed-off-by: David Lamparter <equinox@diac24.net> Cc: Patrick McHardy <kaber@trash.net> Cc: Amit Kumar Salecha <amit.salecha@qlogic.com> Cc: Anirban Chakraborty <anirban.chakraborty@qlogic.com> Cc: linux-driver@qlogic.com Signed-off-by: David S.

2011-06-24qlcnic: Remove holding api lock while taking the dumpAnirban Chakraborty1-3/+5
With the change in logic for taking FW dump across multiple drivers, there is no need to hold onto the api lock anymore in the fw dump path.

2011-06-24qlcnic: Add capability to take FW dump deterministicallySritej Velaga1-8/+24
In presence of multiple functions, current driver implementation does not guarantee that the FW dump is taken by the same function that forces it. Change it by adding a fw reset owner flag that could be changed in the device reset path and only when a function determines that it needs to reset it.

2011-04-13qlcnic: limit skb frags for non tso packetAmit Kumar Salecha1-0/+14
Machines are getting deadlock in four node cluster environment. All nodes are accessing (find /gfs2 -depth -print|cpio -ocv > /dev/null) 200 GB storage on a GFS2 filesystem. This result in memory fragmentation and driver receives 18 frags for 1448 byte packets. For non tso packet, fw drops the tx request, if it has >14 frags. Fixing it by pulling extra frags.
