OFP TCP TIME_WAIT buffer count increment about ofp HOT 3 CLOSED

Hi @manishmatey,

The value for 'pcb_tcp_max' can be configured through OFP configuration file (See OFP_CONF_FILE_ENV).
I see no reason not to propose a similar method for tcptw.. e.g: to permit configuration of tcptw size as value or percentage of global_param->pcb_tcp_max.

You can propose a change (pull request) with this... it will take (near) forever to be reviewed but you may have it.

At least a memory impact is expected as the computed value is used on allocation of V_tcptw_zone (that is an ODP pool).
If memory is not an issue for your setup, you can enable (define) OFP_TCP_MAX_CONNECTION_RATE in ofp_config.h for the default configuration (tcptw size = pcb_tcp_max)

@bogdanPricope Thanks for the reply. I will increase TIME_WAIT buffer and proceed.

@manishmatey You may also check the NFP repo: https://github.com/NetInoSoftware/nfp
NFP is a commercial version of OFP with the 'nfp' repo as 'public'/'demo' part.
API is similar and has a lot of cool features (e.g DHCP IPv4 client).
