e82910570f ETHER: Add support to determine host NIC address without ifconfig 
- Recent Linux versions don't install ifconfig by default and now use
  the new ip command for network details.
- Avoid writing command results to a temp file and use popen instead.

31606161ce SCP: Avoid potential compiler warnings 
Essentially all are non-functional problems but silencing them is a good idea

5e46b298f1 ETHER: Silence several Coverity warnings. 
Most were noise and non-issues, but the change from fclose() to
pclose() was absolutely needed.

A false positive remains regarding tun variable going out of scope.
Under the conditions where a resource leak could occur, the tun
variable is saved in *fd_handle and thus not leaked.

8c57893675 ETHER: Avoid potential compiler warning about version string overrun 
gcc 9.3.0 on Ubuntu 20.04 somehow knows that the length of the
string pcap_lib_version() returns can be 256 bytes long.  It then
generates a warning about truncation potential.  The problematic
code path will only be executed on Windows with an old version of
Npcap, but the compiler can't know that.  Make the local buffer
larger to silence the resulting noise.

721e2f42c5 ETHER: Report Windows Npcap as unsupported in the Ethernet version string 
Current versions of Npcap can talk directly to the host system's network
stack.  This defect was just discovered.  Fortunately, WinPcap 4.1.3 works
as needed and is still functional on Windows 10.

829e64ae67 ETHER: Fix Coverity identified issues 
- Let dynamically loaded (Shared Library) routines do argument checking
  if they've been successfully loaded.
- Properly cast file descriptors into SOCKET when stored in the fd_handle
- Clean up error paths when opening tun/tap transports - potential leaks.
- Avoid possible string overflow when opening a tap device on Linux
- Try another way to ignore a return from fread() without getting
  warnings.

b1f3441f7f ETHER: Start newly opened interfaces blocking all packets 
A device simulator is responsible for specifying exactly what categories of
packets it wants to receive.  It should do that after having opened the device.
This change avoids collecting packets that aren't actually interesting until
after the device designates which packets it is interested in.
