When you generate an Ed25519 key, the comment is embedded in the private key, but there doesn't seem to be a way to change this comment: 

$ ssh-keygen -t ed25519 -N '' -C foobar -f tmp
Generating public/private ed25519 key pair.
Your identification has been saved in tmp.
Your public key has been saved in tmp.pub.
The key fingerprint is:
SHA256:...
The key's randomart image is:
...

$ grep -v ^-- tmp | base64 -d | strings | grep foo
foobar

$ ssh-keygen -c -C moobar -f tmp
Comments are only supported for RSA1 keys.

Changes:
 openssh (1:7.2p1-1) unstable; urgency=medium
 .
   * New upstream release (http://www.openssh.com/txt/release-7.2):
     - This release disables a number of legacy cryptographic algorithms by
       default in ssh:
       + Several ciphers blowfish-cbc, cast128-cbc, all arcfour variants and
         the rijndael-cbc aliases for AES.
       + MD5-based and truncated HMAC algorithms.
       These algorithms are already disabled by default in sshd.
     - ssh(1), sshd(8): Remove unfinished and unused roaming code (was
       already forcibly disabled in OpenSSH 7.1p2).
     - ssh(1): Eliminate fallback from untrusted X11 forwarding to trusted
       forwarding when the X server disables the SECURITY extension.
     - ssh(1), sshd(8): Increase the minimum modulus size supported for
       diffie-hellman-group-exchange to 2048 bits.
     - sshd(8): Pre-auth sandboxing is now enabled by default (previous
       releases enabled it for new installations via sshd_config).
     - all: Add support for RSA signatures using SHA-256/512 hash algorithms
       based on draft-rsa-dsa-sha2-256-03.txt and draft-ssh-ext-info-04.txt.
     - ssh(1): Add an AddKeysToAgent client option which can be set to 'yes',
       'no', 'ask', or 'confirm', and defaults to 'no'.  When enabled, a
       private key that is used during authentication will be added to
       ssh-agent if it is running (with confirmation enabled if set to
       'confirm').
     - sshd(8): Add a new authorized_keys option "restrict" that includes all
       current and future key restrictions (no-*-forwarding, etc.).  Also add
       permissive versions of the existing restrictions, e.g.  "no-pty" ->
       "pty".  This simplifies the task of setting up restricted keys and
       ensures they are maximally-restricted, regardless of any permissions
       we might implement in the future.
     - ssh(1): Add ssh_config CertificateFile option to explicitly list
       certificates.
     - ssh-keygen(1): Allow ssh-keygen to change the key comment for all
       supported formats (closes: #811125).
     - ssh-keygen(1): Allow fingerprinting from standard input, e.g.
       "ssh-keygen -lf -" (closes: #509058).
     - ssh-keygen(1): Allow fingerprinting multiple public keys in a file,
       e.g. "ssh-keygen -lf ~/.ssh/authorized_keys".
     - sshd(8): Support "none" as an argument for sshd_config Foreground and
       ChrootDirectory.  Useful inside Match blocks to override a global
       default.
     - ssh-keygen(1): Support multiple certificates (one per line) and
       reading from standard input (using "-f -") for "ssh-keygen -L"
     - ssh-keyscan(1): Add "ssh-keyscan -c ..." flag to allow fetching
       certificates instead of plain keys.
     - ssh(1): Better handle anchored FQDNs (e.g. 'cvs.openbsd.org.') in
       hostname canonicalisation - treat them as already canonical and remove
       the trailing '.' before matching ssh_config.
     - sftp(1): Existing destination directories should not terminate
       recursive uploads (regression in OpenSSH 6.8; LP: #1553378).
   * Use HTTPS for Vcs-* URLs, and link to cgit rather than gitweb.
   * Restore slogin symlinks for compatibility, although they were removed
     upstream.
