[PATCH 3/4] powerpc/ps3: gelic_udbg: use struct iphdr from <linux/ip.h>

Show all headers | View raw

Instead of defining a local version of struct iphdr use the standard
definition from <linux/ip.h>.

Several fields in the <linux/ip.h> definition have different names:
 - proto -> protocol
 - src -> saddr
 - dest -> daddr
 - total_length -> tot_len
 - checksum -> check

Also, 'ver_len' is composed by 'version' and 'ihl' in <linux/ip.h>.
