Transformation Statistics
|

|
|
|
The xfrm_proc code is a set of statistics showing numbers of packets
|
|
dropped by the transformation code and why. These counters are defined
|
|
as part of the linux private MIB. These counters can be viewed in
|
|
/proc/net/xfrm_stat.

|
|
i.e. Either inbound SPI, address, or IPsec protocol at SA is wrong
