els	Pointer to the IO context.
evt	Event to process.
data	Data to pass in with the transition.

Returns

static

Handle ELS IO request completions.

Description

This callback is used for several ELS send operations.

Parameters

hio	Pointer to the HAL IO context that completed.
rnode	Pointer to the remote node.
length	Length of the returned payload data.
status	Status of the completion.
ext_status	Extended status of the completion.
arg	Application-specific argument (generally a pointer to the ELS IO context).

Returns

For ELS WQE completions, we seem to acquire the sport and node locks in a different order when compared to other code paths. So, acquire the sport lock here to avoid the deadlock.

FW returns the number of bytes received on the link in the WCQE, not the amount placed in the buffer. So, use this info to check if there was an overrun.
