Hi,

what does Centos 7 do with UPD packets having invalid checksums?

Are such packets inevitably dropped?  Does a network card drop them when it 
does checksum verification in hardware even before the packets go anywhere?

In general, if someone were to send me UPD packets with invalid checksums over 
the internet, how far would such packets get?

In particular, how likely it is that SRTP packets sent over the internet over 
UPD could be damaged in such a way that the verification of the authentication 
tag fails when they arrive at the receiver, and how might such damage be 
caused?
