Change Details

Test the following cases, on x86-64 and riscv hardwares: set kernel environment variables, create new vnets, check sysctls unset kernel environment variables, create new vnets, check sysctls ``` root@:~ # kldload -nq if_bridge root@:~ # sysctl net.link.bridge.log_stp net.link.bridge.log_stp: 0 root@:~ # kenv net.link.bridge.log_stp=1 net.link.bridge.log_stp="1" root@:~ # jail -ic vnet persist 4 root@:~ # jexec 4 sysctl net.link.bridge.log_stp net.link.bridge.log_stp: 1 root@:~ # sysctl net.link.bridge.log_stp net.link.bridge.log_stp: 0 root@:~ # kenv -u net.link.bridge.log_stp root@:~ # jexec 4 sysctl net.link.bridge.log_stp net.link.bridge.log_stp: 1 root@:~ # jail -ic vnet persist 5 root@:~ # jexec 5 sysctl net.link.bridge.log_stp net.link.bridge.log_stp: 0 ```

Repeat tests for sysctl `net.inet.tcp.syncache.hashsize` which is in kernel.
