|
*
|
|
* Description:
|
|
* Poll a device "connection" structure for availability of ICMP TX data
|
|
*
|
|
* Input Parameters:
|
|
* dev - The device driver structure to use in the send operation
|
|
* conn - A pointer to the ICMP connection structure
|
|
*
|
|
* Returned Value:
|
|
* None
|
|
*
|
|
* Assumptions:
|
|
* The network is locked.
|
|
* dev is not NULL.
|
|
* conn is not NULL.
|
|
* The connection (conn) is bound to the polling device (dev).
