7 general idea is that porting lwIP to new architectures requires only
8 small changes to a few header files and a new sys_arch
9 implementation. It is also possible to do a sys_arch implementation
12 The sys_arch provides semaphores and mailboxes to lwIP. For the full
15 functionality. Previous versions of lwIP required the sys_arch to
