In general, you don't; most features just happen automatically.  If you
want extended attributes, for example, just mount with -o user_xattr. 
Similarly, ACLs, large file support and so on all just get set
automatically when you request the feature.

The two main exceptions are htree and online resize.  Currently online
resize has to be enabled at mke2fs time, not dynamically.  And htree can
be set with "tune2fs -O dir_index", but if you want to convert existing
directories to the htree format then you also need to run "e2fsck -D" on
the filesystem.
