## Function Documentation

static unsigned long now | ( | ) | `[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:

  ent | pointer to entry to clean (either in HCAM or HTAB)

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.
