+ *
+ * 2010-12-19: add 7832 USB PID ("functionality same as MCS7830"),
+ * per active notification by manufacturer
+ *
+ * TODO:
+ * - support HIF_REG_CONFIG_SLEEPMODE/HIF_REG_CONFIG_TXENABLE (via autopm?)
+ * - implement ethtool_ops get_pauseparam/set_pauseparam
+ * via HIF_REG_PAUSE_THRESHOLD (>= revision C only!)
+ * - implement get_eeprom/[set_eeprom]
+ * - switch PHY on/off on ifup/ifdown (perhaps in usbnet.c, via MII)
+ * - mcs7830_get_regs() handling is weird: for rev 2 we return 32 regs,
+ * can access only ~ 24, remaining user buffer is uninitialized garbage
+ * - anything else?
