net: hsr: use hlist_head instead of list_head for mac addresses
Currently, HSR manages mac addresses of known HSR nodes by using list_head. It takes a lot of time when there are a lot of registered nodes due to finding specific mac address nodes by using linear search. We can be reducing the time by using hlist. Thus, this patch moves list_head to hlist_head for mac addresses and this allows for further improvement of network performance. Condition: registered 10,000 known HSR nodes Before: # iperf3 -c 192.168.10.1 -i 1 -t 10 Connecting to host 192.168.10.1, port 5201 [ 5] local 192.168.10.2 port 59442 connected to 192.168.10.1 port 5201 [ ID] Interval Transfer Bitrate Retr Cwnd [ 5] 0.00-1.49 sec 3.75 MBytes 21.1 Mbits/sec 0 158 KBytes [ 5] 1.49-2.05 sec 1.25 MBytes 18.7 Mbits/sec 0 166 KBytes [ 5] 2.05-3.06 sec 2.44 MBytes 20.3 Mbits/sec 56 16.9 KBytes [ 5] 3.06-4.08 sec 1.43 MBytes 11.7 Mbits/sec 11 38.0 KBytes [ 5] 4.08-5.00 sec 951 KBytes 8.49 Mbits/sec 0 56.3 KBytes After: # iperf3 -c 192.168.10.1 -i 1 -t 10 Connecting to host 192.168.10.1, port 5201 [ 5] local 192.168.10.2 port 36460 connected to 192.168.10.1 port 5201 [ ID] Interval Transfer Bitrate Retr Cwnd [ 5] 0.00-1.00 sec 7.39 MBytes 62.0 Mbits/sec 3 130 KBytes [ 5] 1.00-2.00 sec 5.06 MBytes 42.4 Mbits/sec 16 113 KBytes [ 5] 2.00-3.00 sec 8.58 MBytes 72.0 Mbits/sec 42 94.3 KBytes [ 5] 3.00-4.00 sec 7.44 MBytes 62.4 Mbits/sec 2 131 KBytes [ 5] 4.00-5.07 sec 8.13 MBytes 63.5 Mbits/sec 38 92.9 KBytes Signed-off-by:Juhee Kang <claudiajkang@gmail.com> Signed-off-by:
