commit 1e49d727e4a6ac012625ceb4f550783c632c11a9

    RDMA/cxgb3: wait at least one schedule cycle during device removal.
    
    During a hot-plug LLD removal event or an EEH error event, iw_cxgb3
    must ensure that any/all threads that might be in a cxgb3 exported 
function
    concurrently must return from the function before iw_cxgb3 returns from
    its event processing. Do this by calling synchronize_net().

    cxgb3: fix hot plug removal crash

    queue restart tasklets need to be stopped after napi handlers are 
stopped
    since the latter can restart them.  So stop them after stopping napi.
