// For the First partial add eSEL the SEL Record ID and offset
// value should be 0x0000. The extended data needs to be in
// the form of an IPMI SEL Event Record, with Event sensor type
// of 0xDF and Event Message format of 0x04. The returned
// Record ID should be used for all partial eSEL adds.
//
// This function creates a /tmp/esel file to store the
// incoming partial esel. It is the role of some other
// function to commit the error log in to long term
// storage. Likely via the ipmi add_sel command.
