Subject: [PATCH 2/6] qeth: fix some trace formating issues

From: Thomas Richter <tmricht@...ux.vnet.ibm.com>

This patch fixes trace formatting issues using the
QETH_CARD_TEXT_ macro. The total size of each trace entry
is 8 bytes. Some of the sprintf formats exceed these 8
bytes (for example using abcd:%d and the converted value
needs more than 3 bytes). The solution is to shorten the
text prepending the value or use a different format (%x).
