ipv6: exthdrs: get rid of indirect calls in ip6_parse_tlv()
As presented last month in our "BIG TCP" talk at netdev 0x15,
we plan using IPv6 jumbograms.
One of the minor problem we talked about is the fact that
ip6_parse_tlv() is currently using tables to list known tlvs,
thus using potentially expensive indirect calls.
While we could mitigate this cost using macros from
indirect_call_wrapper.h, we also can get rid of the tables
and let the compiler emit optimized code.
