Hi All!
I made a patch for uClibc-0.9.16 to add next functions:
struct ether_addr *ether_aton(const char *asc)
struct ether_addr *ether_aton_r(const char *asc, struct ether_addr *addr)
char *ether_ntoa(const struct ether_addr *addr)
char *ether_ntoa_r(const struct ether_addr *addr, char *buf)
They just sticked from some glibc files (inet/ether_*.c) to one file.
Note that definitions of this functions has already present in the
uClibc-0.9.16/include/netinet/ether.h
I tested patched library with ebtables, f.e.
Is it possible to include patched files in future library releases?
