Subject: ieee488: flush upper layer payload data when IFC asserts
X-Git-Url: http://sigrok.org/gitweb/?p=libsigrokdecode.git;a=commitdiff_plain;h=8e796681f2e53c819a0257ab6f4db810aba77334

ieee488: flush upper layer payload data when IFC asserts

Also flush previously accumulated payload data when the IFC signal
asserts (interface clear, a controller requests ownership of the bus).
This is in line with EOI (end of message) and ATN (start of a command,
including change of "connected" peers or direction of communication).
