For each configured queue, add a stats counter rxdrop_<queue_id> that reflects the hardware per-queue drop counter where <queue_id> is the queue id in the ConnectX configuration as defined by the user. # Conflicts: # src/apps/mellanox/connectx.lua

…ling Rename cxq.next_rx_cqeid to cxq.rx_cqcc (completion queue consumer counter) and expand to 32 bit. This counter is not wrapped around the size of the cq. It is used to calculate the value of the SW ownership bit directly with efficient bitops and eliminates the need for the rx_mine member of cxq. # Conflicts: # src/apps/mellanox/connectx.lua
The event queue is polled at the frequency of sync_timer(). The
following events are supported:
* CQError. Prints the CQ number and syndrome, then aborts.
* PortStateChange. Prints the port number and new state
(up/down). This could be used to replace the get_port_status()
call in sync_stats()
* PageRequest. Allocates/deallocates the requested number of pages.
