=== Week -2: Implement JMicron driver ===
=== Apr. 28th to May 1st ===
== Day 1 ==
Start to write JMicron Driver.

  * Helper functions
    * jme_reload_eeprom(): Which cause the MAC processor to place MAC Address to register.\\
    * j{read,write}32(): Register reading/writing wrapper.
  * Basic layout.
    * pci_probe: 
      * private data allocation
      * Getting ioport
      * Interface registration
      * Initialize hardware
      * Reading MAC Address
    * pci_remove
      * Interface un-registration
      * Free private data
      * Reset hardware

== Day 2 ==
  * Implement link status check routines.
    * ifstat can show correct cable link status.
  * It'll freeze if IRQ generated on native driver.
  * netdev->link_rc was initiallized in:
    * ''alloc_etherdev() -> alloc_netdev() -> netdev->link_rc = -EUNKNOWN_LINK_STATUS;''

== Day 3 ==
  * Implement receive functions
  * Fount out that we have very small memory poll(128K). Due to receive buffer allocation error. The original design tried to allocate 1024*MTU received buffers.

== Day 4 ==
  * Implement transmit functions
  * netdev_tx_complete{_err}() called free_iob(). So we shouldn't do free_iob() both on successfully transmited or failed to deliver.
