[OE-core] [PATCH] ppp: Add two structures in if_pppol2tp.h

[Chong.Lu at windriver.com]

From: Lu Chong <Chong.Lu at windriver.com>

Some further structure definitions are needed in include/linux/if_pppol2tp.h for
IPv6 support, else we would get the error as below:

	In file included from plugin.c:53:0:
	bitbake_build/tmp/sysroots/intel-x86-64/usr/include/linux/if_pppox.h:84:26:
	error: field 'pppol2tp' has incomplete type
  	  struct pppol2tpin6_addr pppol2tp;
        		          ^
	bitbake_build/tmp/sysroots/intel-x86-64/usr/include/linux/if_pppox.h:99:28:
	error: field 'pppol2tp' has incomplete type
	  struct pppol2tpv3in6_addr pppol2tp;
                		    ^
	make[2]: *** [plugin.o] Error 1
