c3b4a740db qeth: rework TSO functions
The maximum TSO size OSA can handle is 15 * PAGE_SIZE. This
patch reduces gso_max_size to this value and adds some sanity
checks and statistics to the TSO implementation.
Since only layer 3 is able to do TSO move all TSO related functions
to the qeth_l3 module.

d64ecc22d0 qeth: Exploit Connection Isolation
Isolate data connection to a shared OSA card against other data
connections to the same OSA card. Connectivity between isolated
data connections sharing the same OSA card is therefore possible only
through external network gear (e.g. a router).

7c6a3ed5bd qeth: display "undefined" value of sysfs-attribute "layer2"
If nothing has been written into the qeth sysfs-attribute layer2,
its value is "-1" meaning "not yet defined". But the value is
displayed as "1" meaning "layer2 selected". The patch changes the
reading of this "-1"-value to "-1" to make clear the layer2-attribute
has not yet been defined.

Performance measurements showed EDDP does not lower CPU costs but increase
them. So we dump out EDDP code from qeth driver.
