gnome-keyring Saving PIN for PKCS#11 smart card

[Ignat Loskutov <ignat loskutov gmail com>]

Hello,

I'm using a smart card with a certificate for SSH authentication. To avoid entering PIN for each connection, I use `ssh-add -s /path/to/pkcs11/provider.so`. However, I have to repeat this operation each time I log in, while storing the PIN looks like the exact purpose of gnome-keyring. Altough the smart card itself is displayed in Seahorse GUI, it doesn't have an option to save the PIN. Can I save it in some other way?
