DHCP "agent remote id" sub-option 2 of option 82 can already be
configured with [ipoe] / "agent-remote-id". However, it is not
documented.
Add information about agent-remote-id in accel-ppp.conf man.

This patch introduces nas-port-id-in-req switch to disable sending
NAS-Port-Id attribute in radauth and radacct messages. New switch
might be useful if radius server cannot properly handle this
attrubite.

Netlink buffers may overflow so it might be useful to increase send and receive
netlink buffer sizes.
Two parameters to [common] configuration section added: nl-rcv-buffer,
nl-snd-buffer.
It is required to set (sysctl) net.core.wmem_max>=nl-snd-buffer and
net.core.rmem_max>=nl-rcv-buffer before running accel-pppd
To check current netlink buffer size and related info use the following command:
% ss -f netlink -m
0 0 rtnl:kernel * skmem:(r0,rb212992,t0,tb212992,f0,w0,o0,bl0,d0)
0 0 rtnl:-1140221812 * skmem:(r0,rb2048000,t0,tb80000,f0,w0,o0,bl0,d0)
0 0 rtnl:accel-pppd/14285 * skmem:(r0,rb2048000,t0,tb65536,f0,w0,o0,bl0,d0)
...
(Please check man ss to get the meaning for r,rb,t,tb,f,w,o,bl and d params)
In the ss output you will see the values doubled from configured.
First accel-pppd netlink socket will use default values (rcv=1048576, snd=32768)
regardless of configured nl-rcv-buffer and nl-snd-buffer values.

refer #6 for modre details.

usually there's no need to have per-proto limitation, since the need
of max starting limitation affects the whole server, not particular
protocol only.

default stateful ipv6 address & prefix radius attrs are per-rfc6911:
171 Delegated-IPv6-Prefix-Pool
172 Stateful-IPv6-Address-Pool
the single pool name from chap-secret file pool is shared for
ipv4/ipv6/ipv6 dp, new config syntax TBD.
per-proto pool names are still for ipv4 only, new config syntax TBD.

If multisession behavior is managed by accel-ppp and Radius server
ignores the case of the User-Name attribute, it might be required to
ignore the case in accel-ppp to prevent multiple session with
different letter cases.

let check-ip setting from [ppp]/[ipoe] sections has prio over [common]
for compatibility with older configs.

sstp: implement ssl-protocol option and add unsupported features logging
|
|
|
|
|
|
possible protocols are ssl2, ssl3, tls1, tls1.1, tls1.2 and tls1.3,
but support does depend on openssl library.
defaults are up to openssl library w/o ssl2/ssl3.

following bind option formats are valid:
bind=x.x.x.x
bind=2001:db8::1
bind=unix:/var/run/sstp.socket
bind=unix:@sstp
port option is meaningful for ipv4 and ipv6 only

currently the only ssl value is supported

new config options:
[ipoe]
weight=N - global weight
interface=ethX,weight=N - per-interface weight
How it works:
On reception of DHCPDISCOVER accel-ppp sends broadcast DHCP message to port 67 with same xid and add special vendor-specific option
where encodes its current session count multipled by weight.
On reception of such message accel-ppp searches session with same xid and compares weight.
If received weight is less than session's weight then it terminates this session.
per-interface weight=0 has special meaning as backup (fail-over) interface, f.e. it terminates session on any received weight.
By default weight based load balancing is disabled.
To enable need to specify global or/and per-interface weight.

If pool specified with /128 prefix length, then initialize intf_id by gw_ip6_address and peer_intf_id by generated pool address.

config changes:
[ip-pool]
x.x.x.x/mask,name=pool1
y.y.y.y/mask,name=pool2,next=pool1

Reuse exsisting radius functionality and allow set iterface name
template for pppoe/pptp/l2tp, '%d' specification will be replaced
automagically to the next available index by kernel.
PPP interface rename allows to easy differ client's interfaces from
the other ppp ones, for example, with just netfilter interface rules.
Example:
[pptp]
ifname=pptp%d will produce pptp0, pptp1, ...
