Subject: Re: [PATCH 2.6.28] RDMA/cxgb3: deadlock in iw_cxgb3 can cause hang when configuring interface.

Looks good, applied.

However, I think it's a little yucky to call ethtool ops without rtnl,
although it is of course perfectly safe in this case.  It might be nicer
to introduce a new cxgb3 <-> iw_cxgb3 interface that returns the
firmware version, which can also be used to implement the get_drvinfo
ethtool op as well.  That would let you avoid fw_vers_string_to_u64() as
well -- it is a little silly at the moment how cxgb3 converts to a
string and then iw_cxgb3 parses that string.

But that's all much lower priority than just fixing a deadlock.

 - R.
