will try to invoke Snp->GetStatus() to get the media status. If media is already
present, it returns directly. If media is not present, it will stop SNP and then
restart SNP to get the latest media status. This provides an opportunity to get
the correct media status for old UNDI driver, which doesn't support reporting
media status from GET_STATUS command.
Note: there are two limitations for the current algorithm:
1) For UNDI with this capability, when the cable is not attached, there will
be an redundant Stop/Start() process.
2) For UNDI without this capability, when the cable is attached, the UNDI
initializes while unattached. Later, NetLibDetectMedia() will report
MediaPresent as TRUE, causing upper layer apps to wait for timeout time.
2) for UNDI without this capability, in case that network cable is attached when
Snp->Initialize() is invoked while network cable is unattached later,
NetLibDetectMedia() will report MediaPresent as TRUE, causing upper layer
apps to wait for timeout time.
