Fix build issue when compiling with -Wcast-align #27

Closed nhorman closed 4 years ago

nhorman commented 4 years ago

Passing a char buffer cast to struct nlmsghdr * violates the rules of -Wcast-align on some arches, as described in : https://github.com/nhorman/dropwatch/issues/26

Fix it by declaring the buffer as a struct nlmsghdr, and casting to a less alligned type
