Hey Roland, I just noticed that the change it iwch_provider.c in commit f4e91eb4a81559da87a3843758a641b5cc590b65 undid the fix done in commit 7f049f2f4259e4a5c213720df1ce0c2ca095641a. It removed the calls to rtnl_lock() that serialized the iw_cxgb3 ethtool ops calls into the cxgb3 driver. Shall I add a patch to reintroduce the fix? Stevo.
