it is possible to use all filters for a single interface.
Currently ethtool doesn't support modifying filter count so
that user can allocate more filters to a interface and less
to others. This patch adds ETHTOOL_SRXCLSRLCNT ioctl command
for modifying filter count.

example command:
./ethtool -U eth0 rule-count 256

How can use see what the current usage is? How many in total you have
available?  What the current split is between the interfaces?

You say:

   * Jakub suggested if devlink-resource can be used for this.

devlink-resource provides you a standardised mechanism to answer the
questions i just asked. So i would have to agree with Jakub.
