2018-08-13Multiarch handling in different constructor macrosDamjan Marion1-5/+0
This significantly reduces need for ... in multiarch code. Simply constructor macros will jost create static unused entry if CLIB_MARCH_VARIANT is defined and that will be optimized out by compiler.

2018-06-05bond: send gratuitous arp when the active slave went down in active-backup modeSteven1-3/+1
- Modify the API send_ip6_na and send_ip4_garp to take sw_if_index instead of vnet_hw_interface_t and add call to build_ethernet_rewrite to support subinterface/vlan - Add code to bonding driver to send an event to bond_process when the first interface becomes active or when the active interface is down - Create a bond_process to walk the interface and the corresponding subinterfaces to send garp/ip6_na when an event is received. - Minor cleanup in bonding/node.c Note: dpdk bonding driver does not send garp/ip6_na for subinterfaces. There is no attempt to fix it here. But the infra is now done and should be easy to add the support. Change-Id: If3ecc4cd0fb3051330f7fa11ca0dab3e18557ce1 Signed-off-by: Steven <sluong@cisco.com>

2018-05-25bond: performance harvestingSteven1-13/+15
- hash is great. But it is a bit too slow for the DP. Use direct array indexing to quickly retrieve the slave interface. - the algorithm used by flow hash is great. But it is a bit too slow for the DP. Use l2_hash_hash() extracted from lb_hash.h which ECMP is using. It makes use of intrinsic crc32 instruction set. - shortcut modulo arithmetic when the operand is 2**x (where x up to 4) to avoid division instruction. - special case for link count == 1 in bond_tx_fn() - use clib_mem_unaligned to access data for the packet to avoid alignment error - Fix some typos for packet tracing.

2018-04-24lacp: deleting the bond subinterface may cause lacp to lose the partner ↵Steven1-2/+1
[VPP-1251] Problem: When the bond subinterface is removed, it was observed that we lost the lacp partner. Show hardware shows rx counter goes up, but show interface does not for the slave interfaces. Cause: We reset the interface promiscuous mode when the bond subinterface is deleted. This causes dpdk not to accept any packet. Leave the interface in promiscuous mode fixes the problem. Other fixes: There are few places we use hw_if_index as if they are sw_if_index. But they don't necessarily have the same value. As soon as a subinterface is created, they start to diverge. The fix is to use the correct API for the hw_if_index and sw_if_index.

2018-03-30bond: show trace causes a crash if the interface is deletedSteven1-6/+16
For the debug image, if the interface is removed and the trace was collected prior to the interface delete, show trace may cause a crash. This is because vnet_get_sw_interface_name and vnet_get_sup_hw_interface are not safe if the interface is deleted. The fix is to use format_vnet_sw_if_index_name if all we need is to get the interface name in the trace to display. It would show "DELETED" which is better than a crash.

2018-03-21bond: Add bonding driver and LACP protocolSteven1-0/+509
Add bonding driver to support creation of bond interface which composes of multiple slave interfaces. The slave interfaces could be physical interfaces, or just any virtual interfaces. For example, memif interfaces. The syntax to create a bond interface is create bond mode <lacp | xor | acitve-backup | broadcast | round-robin> To enslave an interface to the bond interface, enslave interface TenGigabitEthernet6/0/0 to BondEthernet0 Please see src/plugins/lacp/lacp_doc.md for more examples and additional options. LACP is a control plane protocol which manages and monitors the status of the slave interfaces. The protocol is part of 802.3ad standard. This patch implements LACPv1. LACPv2 is not supported. To enable LACP on the bond interface, specify "mode lacp" when the bond interface is created. The syntax to enslave a slave interface is the same as other bonding modes.
