[qiaojingx]

Description

Ocf connection can't be established on K64F, while ocf works fine on Arduino101.

Test Code

OcfServer.js OcfClient.js OcfSensorServer.js OcfSensorClient.js

Steps to Reproduction

1. make BOARD=frdm_k64f JS=samples/OcfServer.js
2. cp outdir/frdm_k64f/zephyr/zephyr.bin /media/<username>/MBED/
3. Connect PC via Ethernet cable and add router on PC:

ip -6 route add 2001:db8::/64 dev eno1
ip -6 addr add 2001:db8::2 dev eno1

4. ./outdir/linux/release/jslinux samples/OcfClient.js --noexit

Actual Result

Ocf connection can't set up while ping6 2001:db8::1 is ok.

Expected Result

Ocf Client can connect to Ocf Server.

I can fix this by turn on promiscuous mode to get, with patch #1886, this seems to be related to #1868, currently IF_MCAST_IPV6_ADDR_COUNT is already at 4 with OCF and the bug is still reproducible unless you turn on promiscuous mode, maybe @pfalcon have insights on if this is needed?

So, guys, I'm currently digging into other networking issues, and can't look into it, can you please submit a Zephyr ticket on this?
