io-pkt-v4-hc blocking   
When in use QNX6.5 and Intel Ethernet card
...
#io-pkt-v4-hc -de1000
#ifconfig wm0 192.168.1.1 up
...
and we try to send a lot of pings through network

#ping -l 100000 -s1590 192.168.1.2
then  io-pkt-v4-hs stack becomes blocked.

When we try to use another RTL Ethernet card
...
#io-pkt-v4-hc -drtl
#ifconfig en0 192.168.1.1 up
#ping -l 100000 -s1590 192.168.1.2

then  no such blocking occurs.

What could be the reason?

Please post the output from "use -i devnp-e1000.so".

Re: io-pkt-v4-hc blocking   
Please try the attached driver. Also realize that you are trying to send 200000 messages in 1 second, so it might be an 
idea to increase the receive and transmit buffers with the "receive=nnn" and "transmit=nnn" command line options to the 
driver. The defaults for both are 512.

Re: io-pkt-v4-hc blocking   
Dear Hugh, 
your new driver version works mach more stably on the ping test, 
especially with the argument reseave = 4096. 

We will check if this version solves network problems that we occasionally have. 

Thank you very much

Re: io-pkt-v4-hc blocking   
Occasionally we have a problem removing io-pkt-v4-hc from execution with message
...
Process 286737 (io-pkt-v4-hc) terminated SIGSEGV code=1 fltno=11 ip=08101485 (io-pkt-v4-hc@m_free_wtp+0x15) ref=82d1b0ec
.
...

Please explain what could be the reason?

Could there be a problem with devnp-e1000.so?

Could there be a reason for the malfunction of the Etnernet interface chip ?

Core dump , use -i io-pkt-v4-hc and Error message photos attached to this Message.
