Derivate socketcan to multiple child depending upon socket CAN type.
Use to initialize raw, bcm and later isotp socket. Now we should have, 1 BCM socket by signal to make filter on them. 1 raw socket by devices is kept to use diagnostic manager as is. Change-Id: Icb2daddf67039479f72bc487d53971adc9aba638 Signed-off-by: Romain Forlot <romain.forlot@iot.bzh>
