Hello, F-stack team
I'm trying to run your solution with a load balancer with intel nic. I have two servers that are connected to each other.
My target is to run 2 web servers and 1 nlb on the server with IP 10.20.22.23 and curl data from the server 10.20.22.72
I've bind my device with vfio-pci driver:
[root@localhost nginx_fstack]# /root/dpdk/usertools/dpdk-devbind.py -s
Network devices using DPDK-compatible driver
============================================
0000:48:00.2 'I350 Gigabit Network Connection 1521' drv=vfio-pci unused=igb
Then I ran f-stack with next config:
[dpdk]
# Hexadecimal bitmask of cores to run on.
lcore_mask=1c
# Number of memory channels.
channel=4
# Specify base virtual address to map.
#base_virtaddr=0x7f0000000000
# Promiscuous mode of nic, defualt: enabled.
promiscuous=1
numa_on=1
# TX checksum offload skip, default: disabled.
# We need this switch enabled in the following cases:
# -> The application want to enforce wrong checksum for testing purposes
# -> Some cards advertize the offload capability. However, doesn't calculate checksum.

# TCP segment offload, default: disabled.
tso=0

# sent packet delay time(0-100) while send less than 32 pkts.
# default 100 us.
# if set 0, means send pkts immediately.
# if set >100, will dealy 100 us.
# unit: microseconds
pkt_tx_delay=100
# use symmetric Receive-side Scaling(RSS) key, default: disabled.

Basic scenario, when I ran your web-server (/usr/local/nginx_fstack/conf/nginx.conf) on the server .23 and curl data from the server .72 worked properly:
[root@localhost nginx_fstack]# curl 192.168.1.2:1180
