In send_atomic_ack function, it is not necessary to make a
skb_clone. To gain better performance (high throughput and
low latency), this skb_clone is removed.
The following tests are made.
server client
--------- ---------
1.1.1.1|<----rxe-channel--->|1.1.1.2|
--------- ---------
On server: rping -s -a 1.1.1.1 -v -C 1000 -S 512
On client: rping -c -a 1.1.1.1 -v -C 1000 -S 512
The kernel config CONFIG_DEBUG_KMEMLEAK is enabled on both server
and client.
This test runs for several hours. There is no memory leak and the whole
system can work well.
As the above network, the following tests are made.
Server: ibv_rc_pingpong -d rxe0 -g 1
Client: ibv_rc_pingpong -d rxe0 -g 1 1.1.1.1
The result on Server(10 tests are made).
Before:
Throughput is 137.07 Mbit/sec
Latency is 517.76 usec/iter
After:
Throughput is 148.85 Mbit/sec
Latency is 476.64 usec/iter
The throughput is enhanced and the latency is reduced.

V2-->V3: Fix typo errors.
V1-->V2: 10 tests are made. From throughput and latency, the performance is better.
Hi Jason,
I see that the state of this patch in patchworks is Changes Requested,
but from what I can see, the changes were requested of v2 and
implemented in v3. Was the state of this patch in patchworks switched
by accident possibly, or is there something you were waiting on for the
v3 patch?
Hi, All
I am making tests with the comments from Yonatan. After the tests are
over, I will make V4 patch.
