99 2. shut down FEC after network transfers
101 1. A new test command was added. This is a simplified version of
102 the one in the bourne shell.
103 2. A new exit command was added which terminates the current
105 3. Fixed handing of $? (exit code of last executed command)

120 - add support for NETTA and NETPHONE boards; fix NETVIA board
121 - add support for the Epson 156x series of graphical displays
122 (These displays are serial and not suitable for using a normal
123 framebuffer console on them)
124 - add infrastructure needed in order to POST any DSPs in a board
125 - improve and fix various things in the MPC8xx FEC driver:
126 1. The new 87x and 88x series of processors have two FECs,
127 and the new driver supports them both.
128 2. Another change in the 87x/88x series is support for
129 the RMII (Reduced MII) interface. However numerous
130 changes are needed to make it work since the PHYs
131 are connected to the same lines. That means that
132 you have to address them correctly over the MII
134 3. We now correctly match the MII/RMII interface
135 configuration to what the PHY reports.
136 - Fix problem when readingthe MII status register. Due to the
137 internal design of many PHYs you have to read the register
138 twice. The problem is more apparent in 10Mbit mode.
139 - add new mode ".jffs2s" for reading from a NAND device: it just
140 skips over bad blocks.
141 - add networking support for VLANs (802.1q), and CDP (Cisco
143 - some minor patches / cleanup

1647 o correctly extends the timeout depending on the size of all
1648 queued messages for both transmit and receive
1649 o will not continue with receive if transmit times out
1650 o ensures that the error callback is done for all queued tx

1653 the callback, and does not overwrite an earlier error
1654 o logic in i2c_probe now correct
