l2_packet: Add build option to disable Linux packet socket workaround
Linux packet socket workaround(*) has an impact in performance when the workaround socket needs to be kept open to receive EAPOL frames. While this is normally avoided with a kernel that has the issue addressed by closing the workaround packet socket when detecting a frame through the main socket, it is possible for that mechanism to not be sufficient, e.g., when an open network connection (no EAPOL frames) is used. Add a build option (CONFIG_NO_LINUX_PACKET_SOCKET_WAR=y) to disable the workaround. This build option is disabled by default and can be enabled explicitly on distributions which have an older kernel or a fix for the kernel regression. Also remove the unused variable num_rx. (*) Linux kernel commit 576eb62598f10c8c7fd75703fe89010cdcfff596 ('bridge: respect RFC2863 operational state') from 2012 introduced a regression for using wpa_supplicant with EAPOL frames and a station interface in a bridge.
