Re: [lng-odp] [API-NEXT PATCH v1 1/1] pktio APIs to set the MAC address and MTU size.

As agreed during today's ODP Public call: APIs for MTU capability and setting OK. Applications should remember that in most cases they will not be authorized to set the MTU since this relates to physical properties of the interface. odp_pktio_capability() should report number of mac addrs

Re: [lng-odp] [API-NEXT PATCH v1 1/1] pktio APIs to set the MAC address and MTU size.

Hi, In DPDK case, default MTU is 1500: /* * Set the default MTU. */ eth_dev->data->mtu = ETHER_MTU; where: #define ETHER_MTU \ (ETHER_MAX_LEN - ETHER_HDR_LEN - ETHER_CRC_LEN) /**< Ethernet MTU. */ So, if you need to jumbo, you have to set MTU yourself (I guess dpdk will

Re: [lng-odp] [API-NEXT PATCH v1 1/1] pktio APIs to set the MAC address and MTU size.

Hi, I think MAC addresses and MTU are a bit different. There are valid use cases for application wanting to set the MAC address, even dynamically. For instance, with VRRP one wants to receive packets destined to a VRRP MAC address in addition to the fixed MAC address of a port. The

Re: [lng-odp] [API-NEXT PATCH v1 1/1] pktio APIs to set the MAC address and MTU size.

Hi, I think we need both MTU and MAC address to be settable from ODP. In OFP, at some point I was considering using tap pktio instead of ofp tap interface for slow path processing - not being able to set MAC address was A problem. What about DHCP by MAC address? Maybe there are systems where

Re: [lng-odp] [API-NEXT PATCH v1 1/1] pktio APIs to set the MAC address and MTU size.

Hi Bill The reasons below dont jive with what ODP does today. If the routines odp_pktio_mtu() and odp_pktio_mac_addr() exist today. They assume that MTU can be configured and returned to the datapath. As an application developer, it does make sense for me to use 2 different paths to talk

Re: [lng-odp] [API-NEXT PATCH v1 1/1] pktio APIs to set the MAC address and MTU size.

Hi, ODP API should somewhere define what exactly MTU means in the context of ODP. One can guess that transmission and reception of L2 frames larger than the configured MTU is not guaranteed to succeed, but which bytes are taken into account? For instance, is Ethernet FCS counted towards the
