[inline, static]

Returns number of seconds since the epoch.

static struct filtering_entry* rtu_fe_clean

(

struct filtering_entry *

ent )

[static, read]

Cleans MAC entry from mirror MAC table. All entry fields are reset.

Parameters:

Returns:

pointer to filtering entry that was cleaned

static struct filtering_entry* rtu_fe_copy	(	struct filtering_entry *	dst,
		struct filtering_entry *	src
	)		[static, read]

Copies src filtering entry body into dst filtering entry body.

Returns:

pointer to dst filtering entry.
