Taxes after acquisition

The recent Broadcom/VMware acquisition took 52.1% of

my VMW shares and gave me .252 AVGO shares.  The other 47.9% of my shares were cashed out for 142.50.  Most things I read are in regards to Cash 2 boot, but i am not 100% sure that applies because that is normally stock and some cash per share. This is pretty important because it means either paying cap gains on just the cash portion versus doing the cash 2 boot exercise and resetting basis and treating all of the cash as the gain.  Would

love some thoughts on this.   The Broadcom 8937 implies the lattwr but says it should not be considered Tax advice.
