The networking code in Kernel 2.4

[Bernhard Jansen <bjansen@xxxxxx>]

Hi,

I have a little problem with the new networking code in kernel 2.4 . In
the 2.2 kernels was the dev->tbusy variable to make sure that
the dev->hard_start_xmit funktion is not called next before the old
packet is completly sent out.  My problem is that I wanna write a driver

for a Siemens or better now an Infinion chip called ESCC2, it's for sync
serial communication,  it have a 32 byte deep FIFO what actually problem
is. Because I get a packet from the upper layer and which is normally
bigger than 32 byte, I write the first 32 byte out to the chip and then
I have to wait for an interrupt that the FIFO is ready again. The spot
of my problem is how can I make sure that dev->hard_start_xmit
funktion is not called again form the kernel until the whole buffer is
sent out.

Thanks in advance
