You do not need to specify a nexthop gateway with the spec_nh (lsp) commands

ip route add 192.168.2.0/24 dev eth0 spec_nh 0x8847 0x2
ip route add 192.168.2.0/24 via 192.168.1.1 spec_nh 0x8847 0x2

Are equivalent commands.  The nexthop IP is never use when there is a spec_nh
(lsp).

Sure.  44939 bytes divided by 484 is approximately 92 bytes per packet, that is
reasonable.
