* IUCV base support.
*
* S390 version
* Copyright (C) 2000 IBM Corporation
* Author(s):Alan Altmark (Alan_Altmark@us.ibm.com)
* Xenia Tkatschow (xenia@us.ibm.com)
*
*
* Functionality:
* To explore any of the IUCV functions, one must first register
* their program using iucv_register_program(). Once your program has
* successfully completed a register, it can exploit the other functions.
* For furthur reference on all IUCV functionality, refer to the
* CP Programming Services book, also available on the web
* thru www.ibm.com/s390/vm/pubs, manual # SC24-5760
*
* Definition of Return Codes
* -All positive return codes including zero are reflected back
* from CP except for iucv_register_program. The definition of each
* return code can be found in CP Programming Services book.
* Also available on the web thru www.ibm.com/s390/vm/pubs, manual # SC24-5760
* - Return Code of:
* (-EINVAL) Invalid value
* (-ENOMEM) storage allocation failed
* pgmask defined in iucv_register_program will be set depending on input
* paramters.

---help---
This option adds a `TCPMSS' target, which allows you to alter the
MSS value of TCP SYN packets, to control the maximum size for that
connection (usually limiting it to your outgoing interface's MTU
minus 40).
This is used to overcome criminally braindead ISPs or servers which
block ICMP Fragmentation Needed packets. The symptoms of this
problem are that everything works fine from your Linux
firewall/router, but machines behind it can never exchange large
packets:
1) Web browsers connect, then hang with no data received.
2) Small mail works fine, but large emails hang.
3) ssh works fine, but scp hangs after initial handshaking.
Workaround: activate this option and add a rule to your firewall
configuration like:
iptables -A FORWARD -p tcp --tcp-flags SYN,RST SYN \
-j TCPMSS --clamp-mss-to-pmtu
To compile it as a module, choose M here. If unsure, say N.
