staging: Add driver to support wanPMC-CxT1E1 card.
Obviously still needs serious attention, but it compiles. Original author: Rick Dobbs Add driver to support wanPMC-CxT1E1 card. This card provides 1-4 ports of T1E1 in PMC form factor. Note, Rick doesn't want his email showing up as the "From:" author, but has given his blessing to have the code included in the kernel tree.

+ This driver supports the SBE wanPMC-CxT1E1 1, 2 and 4 port T3
+ channelized stream WAN adapter card which contains a HDLC/Transparent
+ mode controller.
+
+ If you want to compile this driver as a module

+ * How to be a proc read function
+ * ------------------------------
+ * Prototype:
+ * int f(char *buffer, char **start, off_t offset,
+ * int count, int *peof, void *dat)
+ *
+ * Assume that the buffer is "count" bytes in size.
+ *
+ * If you know you have supplied all the data you
+ * have, set *peof.
+ *
+ * You have three ways to return data:
+ * 0) Leave *start = NULL. (This is the default.)
+ * Put the data of the requested offset at that
+ * offset within the buffer. Return the number (n)
+ * of bytes there are from the beginning of the
+ * buffer up to the last byte of data. If the
+ * number of supplied bytes (= n - offset) is
+ * greater than zero and you didn't signal eof
+ * and the reader is prepared to take more data
+ * you will be called again with the requested
+ * offset advanced by the number of bytes
+ * absorbed. This interface is useful for files
+ * no larger than the buffer.
+ * 1) Set *start = an unsigned long value less than
+ * the buffer address but greater than zero.
+ * Put the data of the requested offset at the
+ * beginning of the buffer. Return the number of
+ * bytes of data placed there. If this number is
+ * greater than zero and you didn't signal eof
+ * and the reader is prepared to take more data
+ * you will be called again with the requested
+ * offset advanced by *start. This interface is
+ * useful when you have a large file consisting
+ * of a series of blocks which you want to count
+ * and return as wholes.
+ * (Hack by Paul.Russell@rustcorp.com.au)
+ * 2) Set *start = an address within the buffer.
+ * Put the data of the requested offset at *start.
+ * Return the number of bytes of data placed there.
+ * If this number is greater than zero and you
+ * didn't signal eof and the reader is prepared to
+ * take more data you will be called again with the
+ * requested offset advanced by the number of bytes
+ * absorbed.
