currently the only ssl value is supported

 if not set, fallback to private key in the same ssl-pemfile

 Warning: config options are changed aligned with general accel-ppp style.
 Following cases, including no-openssl build are supported:

  ssl | ssl-pemfile | behavior
  1     set           get both sha1 & sha256 from the certificate
  0     set           get both sha1 & sha256 from the certificate
  0     unset         use cert-hash-sha1 and/or cert-hash-sha256 hex options
  no-openssl          use cert-hash-sha1 and/or cert-hash-sha256 hex options

 cert-hash-sha1 and/or cert-hash-sha256 hex options override certificate's,
 so it's possible to turn certficate hash verification off with just empty
 values (default).

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, ...

[ppppd-compat]
fork-limit=N

Specifies number of simultaneously running background processes.

introduced new config option:
[ipoe]
vendor=Name

this affects to all attributes specified in attr-xxx options

new config option:
[common]
max-sessions=N

If set then accel-pppd stops reply to new connection requests if total number of sessions (active and starting) is reached specified limit.

This reverts commit 88a90897.

new config option:
[common]
max-sessions=N

If set then accel-pppd stops reply to new connection requests if total number of sessions (active and starting) is reached specified limit.

This reverts commit 88a90897.

new config option:
[common]
max-sessions=N

If set then accel-pppd stops reply to new connection requests if total number of sessions (active and starting) is reached specified limit.

This reverts commit 9ea88bac.

new config option:
[common]
max-sessions=N

If set then accel-pppd stops reply to new connection requests if total number of sessions (active and starting) is reached specified limit.

To keep clients from losing adresses, T1 should be set less that lease time.

If set to 1 then allocate unit (interface) before authorization, so Nas-Port and Nas-Port-Id would be defined in Access-Request phase

If start=auto is specified then accel-pppd automatically starts session with username = interface name on shared=0 interfaces.
Use it with conjuction vlan_mon. So any packet may start session.

local-net is used to filter incomming packets which may start UP session

introduced new module "vlan-mon"

This option specifies value of Calling-Station-Id value.
Available options are 'mac' and 'ip'.
