[support] MR Flag Prob

[Ben McCarthy]

Hi Romain,

I have actually just found the problem. The device I am using is big endian
and therefore the value of IP6_MH_BU_MR gets set to 0x0400. However, mob_rtr
in the home_addr_info struct is only set to be a uint8_t so 400 is too big
for it. Setting it to a uint16_t solves the problem.

I am only using umip 0.3 so this may have been solved in 0.4, if not what do
you think is the best permanent fix? Change the mob_rtr variable or change
the values of IP6_MH_BU_ETC to all fit in uint8_t?

Cheers,

Ben
