RHOSP13- R5.0-214- SRIOV- agent is not coming up, issue while sourcing network-functions-vrouter in agent-functions.sh

[alok kumar]

For SRIOV setup, agent is not coming up.

Error seen in agent log:

docker logs 479049ab979b:

/agent-functions.sh: line 3: /network-functions-vrouter-vrouter: No such file or directory
INFO: agent started in vrouter mode
INFO: vhost0 is already up
INFO: Kernel version does not support the driver required for vrouter to vrouter encryption
/agent-functions.sh: line 151: get_iface_mac: command not found
/agent-functions.sh: line 173: get_iface_mac: command not found
ERROR: either phys nic or mac is empty: phys_int='vhost0' phys_int_mac=''

Issue seems to be in value of AGENT_MODE, which is set to 'vrouter' and corresponding file network-functions-vrouter-vrouter is not found.

agent-functions.sh:
    source /network-functions-vrouter-${AGENT_MODE}

as a workaround, removing "-${AGENT_MODE}" in agent-functions.sh and restarting docker worked fine for me.

Fixed sriov in kernel mode

- in containers 'kernel' mode is used instead of vrouter
that leads to errors like 'missing network-functions-vrouter-vrouter'

- revert checks for dpdk: use wellknow word dpdk instead of
vrouter/kernel to define conditions like is_dpdk
