Bug 26018

There is not Ping communication with an outside host when I use ATM NIC "PCA-200E" made by Fore Systems with FreeBSD4.2.
I go so that a packet does loss by a Ping command in Problem Report kern/23620, but it is the state that return cannot receive at all even if I let you fly in a packet to an outside host in case of this time.
Because I let you go by way of an ATM switch whether you send in a packet and check it, there is not a mistake.

Fix: It was settled if I hit ProbremReport kern/23620 with the patch which appeared, but unfortunately it has been reject even if I hit it with a patch as it is.
I succeed when I guess this right with FreeBSD4.2 because I made the following patches.



Note)
There is not a change that 23620 is reporting contents coming out.
I cannot know that I am different if I let it is only a date of a file and spread it whether I am ignorance.--EQUpiDCbvGZnTN1OU2O55Bd2E3DeMORj618FY1DxfLDIEzSb

How-To-Repeat: Compile kernel with the following ATM options
options         ATM_CORE
options         ATM_IP
options         ATM_SIGPVC
options         ATM_SPANS
options         ATM_UNI
device          hfa

Initialize ATM normally:
fore_dnld¡¡-i hfa0 -d /etc
atm set netif hfa0 nia 1
atm attach hfa0 SIGPVC
ifconfig nia0 192.168.1.1.up
atm add pvc hfa0 0 100 aal5 llc ip nia¡¡192.168.1.2

Now Ping host "192.168.1.2" on the ATM Network.

However, after ping command execution, as for the message, nothing is displayed.
