[ Upstream commit ed779fe4c9b5a20b4ab4fd6f3e19807445bb78c7 ]
After the blamed commit, the member key is longer 4-byte aligned. On platforms that do not support unaligned access, e.g., MIPS32R2 with unaligned_action set to 1, this will trigger a crash when accessing an IPv6 pneigh_entry, as the key is cast to an in6_addr pointer.
Change the type of the key to u32 to make it aligned.
