Our QNX (Version 6.3.0 SP2) Driver hangs up in an application running a micrel ksz 8841-pmqli 
in 10MBit simplex mode when much traffic is done.

Operating system:	QNX 6.3.0 SP2
			
Driver:			NAME=devn-micrel8841.so
			DESCRIPTION=micrel8841 ethernet driver
			DATE=2007/08/30-14:47:26-EDT
			STATE=stable
			HOST=worldbuild
			USER=pspbuild
			Version=630SP3-685
			TAGID=1602

Opreating mode:		10MBit half duplex

Problem description:	The data transfer stops at high data rates (for example at continuous text output
			in a terminal window). Then Phindows closes the the socket.
			If this problem occurs, no more ping is possible on this interface.

Observations:		The hardware produces still interupts and these interrupts are also still 
			received by the kernel !
			But the driver cannot resume the data transfer
			An umount of the driver followed by a mount of the driver fixes the problem !
			In other words: it is NO HARDWARE PROBLEM, but a driver problem.

			If we start the driver using a verbose level < 0xA, a singular output is recorded in the syslog.
			If we start the driver using verbose level 0xA, also a singular output is recorded in the syslog,
			but data rate becomes much reduced, and the drivers does not hang up.




The board architectural structure is as follows:

(The board MEPME2 contains two controllers of type micrell8841.)
