2022-10-13l2: coverity complains dead codesSteven Luong1-14/+11
Coverity complains dead codes in 2 places due to a recent commit as pointed out in Fixes. The dead codes are if (seed < L2_BD_ID_MAX % 2) is_seed_low = 1; and if (is_seed_low) seed += (2 * (i % 2) - 1) * i; seed can never be less than (L2_BD_ID_MAX % 2). Consequently, is_seed_low is always 0. There is also other problem. The inner loop is iterating only once. The fix is to greatly simplify the code to generate a random bd_id.

2020-09-14l2: allocate l2fib only when neededDamjan Marion1-0/+4
Currently l2 fib allocates 512MB hash table unconditionally on startup. This patch postpones table creation up to the point where first interface is put into l2 mode or mac entry is added. In addition it reduces default table size to 128MB and increases number of buckets 4 times. This default setting should be enough to keep 1M mac entries. Also, new startup.conf section is added which allows user to change memory and bucket size. .i.e: l2fib { table-size 512M num-buckets 524288 } Type: improvement Change-Id: I2a29209aa3545181f0087544c97a54d8157b6ec5 Signed-off-by: Damjan Marion <damarion@cisco.com>

2019-01-07L2 BD API to flush all IP-MAC entries in the specified BDJohn Lo1-11/+37
Implement API/CLI to clear IP-MAC tables used for ARP-termination in the specified bridge domain. The CLI to flush MAC IP tables for a BD is: set bridge-domain arp entry <bd-id> del-all The API added is bd_ip_mac_flush.

2017-08-03Add support for API client to receive L2 MAC eventsJohn Lo1-31/+6
Added APIs want_l2_macs_events and l2_macs_event to allow an API client to receive notification events from VPP for MAC learned or aged in L2FIB. Only one API client is allowed for L2 MAC events. The want_l2_macs_events API allow caller to specify MAC learn limit, event scan delay and max number of MACs that can be included in a event message. These parameters should be choosen properly as to not have too many MAC events sent by VPP and overwhelm the API share memory. They can all be left as 0's so VPP will setup reasonable defaults which are: 1000 learn limit, 100 msec scan delay and 100 MACs per event message. If want_l2_macs_events is never called, VPP learning and aging should behave as before except that MAC entries provisioned by API or CLI will not be aged, even if it is not set as static_mac. These non static MACs, however, can be overwritten by MAC learning on a MAC move as a leared MAC. Only learned MACs are subject to aging.
