Ethernet SFP.

# Test for FEAT-376 - Allow/block SFPs
#
# Short description
# - Check HGW has copper SFP which is allowed.
# - Instruct HGW to block all SFPs.
# - Simulate the SFP is replugged.
# - Check that SFPs and Ethernet in TR-181 DM both show the SFP as NotAllowed.
# - Instruct the HGW to allow all SFPs.
# - Simulate the SFP is replugged.
# - Check that SFPs and Ethernet in TR-181 DM no longer show the SFP as
# NotAllowed.
#
# Detailed description
# - Check we're on the right board.
# - Check the current situaton:
# - Check a copper Ethernet SFP is present in the 1st SFP cage and that it's
# allowed.
# - Check Ethernet.Interface.1.SFPReferenceList refers to the 1st cage.
# - Check Ethernet.Interface.1.Status is different from NotAllowed.
# - Check SFPs.AllowAllSFPs has default values:
# - Check SFPs.AllowedSFPs.AllowAllSFPs is 1
# - Check SFPs.AllowedSFPs.AllowedSFP is empty
# - Change SFPs.AllowedSFPs.AllowAllSFPs to 0.
# - Simulate SFP is unplugged.
# - Check SFPs DM indicates no SFP is present.
# - Simulate SFP is replugged.
# - Check HGW does not allow the SFP:
# - Check SFPs DM shows the SFP as not allowed.
# - Check Ethernet.Interface.1.Status is NotAllowed.
# - Change SFPs.AllowedSFPs.AllowAllSFPs to 1.
# - Simulate SFP is replugged.
# - Check HGW allows the SFP
# - Check SFPs DM shows the SFP as not allowed.
# - Check Ethernet.Interface.1.Status is different from NotAllowed.
#
# To simulate an SFP is replugged, the test uses knowledge on how tr181-sfp
# determines SFP presence.
#
# The main purpose of the test is to check interaction between tr181-sfp and
# tr181-ethernet. Therefore the test only changes SFPs.AllowedSFPs.AllowAllSFPs
# to block/allow SFPs. It does not use the table SFPs.AllowedSFPs.AllowedSFP.
# Allowing/blocking SFPs via that table is already covered by the unit tests of
# tr181-sfp.
