+TCPMSS target support
+CONFIG_IP_NF_TARGET_TCPMSS
+ 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

Adaptec AIC7xxx chipset SCSI controller support

+ This driver supports all of Adaptec's PCI based SCSI controllers (not

+ EISA and VLB SCSI controllers (the 274x and 284x series). This is

+CONFIG_AIC7XXX_CMDS_PER_DEVICE
+ Specify the number of commands you would like to allocate per SCSI

+
+ This is an upper bound value for the number of tagged transactions
+ to be used for any device. The aic7xxx driver will automatically
+ vary this number based on device behavior. For devices with a
+ fixed maximum, the driver will eventually lock to this maximum
+ and display a console message inidicating this value.

-Delay in seconds after SCSI bus reset
-CONFIG_AIC7XXX_RESET_DELAY
- This sets how long the driver will wait after resetting the SCSI bus
- before attempting to communicate with the devices on the SCSI bus

- as well as after any reset that might occur during normal operation.
- Reasonable numbers range anywhere from 5 to 15 seconds depending on

- after a bus reset to be ready for the next command, but most hard
- drives and CD-ROM devices are ready in only a few seconds. This
