Upstream changelog:
https://matt.ucc.asn.au/dropbear/CHANGES

This adds elliptic curve cryptography (ECC) support as an option, disabled
by default.

dropbear mips 34kc uClibc binary size:
before: 161,672 bytes
after, without ECC (default): 164,968
after, with ECC: 198,008

help
Enables elliptic curve cryptography (ECC) support in key exchange and public key
authentication.
Key exchange algorithms:
ecdh-sha2-nistp256
ecdh-sha2-nistp384
ecdh-sha2-nistp521
curve25519-sha256@libssh.org
Public key algorithms:
ecdsa-sha2-nistp256
ecdsa-sha2-nistp384
ecdsa-sha2-nistp521
Does not generate ECC host keys by default (ECC key exchange will not be used,
only ECC public key auth).
Increases binary size by about 36 kB (MIPS).
