stephen hemminger 732e49850c netvsc: fix race on sub channel creation ... The existing sub channel code did not wait for all the sub-channels to completely initialize. This could lead to race causing crash in napi_netif_del() from bad list. The existing code would send an init message, then wait only for the initial response that the init message was received. It thought it was waiting for sub channels but really the init response did the wakeup. The new code keeps track of the number of open channels and waits until that many are open. Other issues here were: * host might return less sub-channels than was requested. * the new init status is not valid until after init was completed.
