[ofw] [patch] [ipoib_NDIS6_CM] The send_lock is being held once __send_cb is calling __send_complete_net_buffer.

[Smith, Stan]

Hi Tzachi,
  A couple of questions:

Why is p_port->send_lock is required to be unlocked when calling NdisMSendNetBufferListsCompleteX() which translates to NdisMSendComplete() call?

If p_port->send_lock is required to be unlocked when calling NdisMSendNetBufferListsCompleteX(), then ipoib_port_resume() should call
__send_complete_net_buffer( s_buf, NDIS_STATUS_FAILURE, NDIS_SEND_COMPLETE_FLAGS_DISPATCH_LEVEL, TRUE)  not FALSE
as send_lock is held over calls to ipoib_port_resume().

stan.
