Changes from 1.2.0 to 1.2.1

These changes are archived on ftp.crynwr.com:pub/kchanges and http://www.crynwr.com/kchanges. I cannot answer questions about Linux -- I merely summarize the kernel patches after reading them. I try to make them useful to everyone, but kernel hackers should take them with a grain of salt and read the patches themselves. The patch file is patch-1.2.1.gz

• drivers/block/Makefile fixed for easier module compilation.
• SBPCD Auto-probing stops if an address of 0 is seen (to be entered with the kernel command line). Made the driver "loadable". If used as a module, "audio copy" is disabled, and the internal read ahead data buffer has a reduced size of 4 kB; so, throughput may be reduced a little bit with slow CPUs.
• IDE driver changes: fix ide_error() handling of BUSY_STAT, fix byte-swapped cdrom strings (again.. arghh!), ignore INDEX bit when checking the ALTSTATUS reg.
• Official escape sequence for UTF-8 will probably be .
• Initialize Cyclades defaults for receive threshold and stale data timeout;
• Fix other small Cyclades bugs.
• Don't reset the line if there is no termios structure because we've just released it.
• EtherNext UTP8 added to list of NE2000 clones.
• Updated and corrected firewalling code: the plain 1.2.0 firewall code is simply broken. 1.2.1 is a must if you're firewalling.
• More control added over ARP proxying.
• Fix a bug in IPX that would overwrite memory if a broadcast was received by mistake.
