Synopsis
int gnet_stats_start_copy_compat(struct sk_buff *skb, int type, int tc_stats_type, int xstats_type, spinlock_t *lock, struct gnet_dump *d, int padattr);Arguments
skb
-
- socket buffer to put statistics TLVs into
type
- TLV type for top level statistic TLV
tc_stats_type
- TLV type for backward compatibility struct tc_stats TLV
xstats_type
- TLV type for backward compatibility xstats TLV
lock

Description
Initializes the dumping handle, grabs the statistic lock and appends an empty TLV header to the socket buffer for use a container for all other statistic TLVS.
The dumping handle is marked to be in backward compatibility mode telling all gnet_stats_copy_XXX functions to fill a local copy of struct tc_stats.
Returns 0 on success or -1 if the room in the socket buffer was not sufficient.
