People don't quit *using* hardware just because a company has quit selling it. When we can quit supporting it is more about whether customers ask for support (or our records indicate lots of systems use the hardware) than about whether the vendors still care. That said, we probably could have dropped cxgb3 from 8.0, but I'm not positive about that. Just a guess. --=20 Doug Ledford GPG KeyID: B826A3330E572FDD Fingerprint =3D AE6B 1BDA 122B 23B4 265B 1274 B826 A333 0E57 2FDD --=-fJp7rziJk7MJM4rnRMhh Content-Type: application/pgp-signature; name="signature.asc" Content-Description: This is a digitally signed message part Content-Transfer-Encoding: 7bit -----BEGIN PGP SIGNATURE----- iQIzBAABCAAdFiEErmsb2hIrI7QmWxJ0uCajMw5XL90FAl2qJc8ACgkQuCajMw5X L93eKRAAgIyQHmD2efzM4tMIiAfuMkwIWaI8u/55WWmWPTCGBEB3WPuLXE1K6GOu MUhEXmI0AGIPJRcyQmpCYRHgtnWZFQS+7CnDNElF3qS3+dE57bZ7n3bsXAAIb/4R pBZI+X/JDIv6hs6XjXeqirZIKMfSiT7zBjNsJ5rtgVfpJFlZ0dM8FeD7vmD+BcAf xBDFYe8ISXFqtWG9DZvwyNRsqffY4bTKaqzmeXtKbKAKojRzmtnBAWImush63JAL 7S5SMhQCYlcXDrdXjVWGuiuZT4HZEytCOozo3JMx2up8sAH1hnU/X9lVD9kaNBno 3MG4rOFXRfqwsk6IZsa74JMOWcpUQ0JbVgoefEDBJUhS4NZQLQiA+9HiJctkggGq +mi2VeKxBCoPRvKit7bYTc+gJFjK6N6fHmCbVo0+9NaNl1WpRCBx6mvmZyoARJRV EzakjBc2rkC0swmr4EAtcRFYt/2NpSiAUyLeWjqIcNeN7VUiVwzqFMQV7wZ2RBR0 AakQXKBqrsbKYVIsnjiSx24rPKCHLr0mIx5LsmikF3JVUJqIwmXaLSVl2TtqXl7y 1CwZjkS32Ym8f7C7Ub9Jhq5O3lslUoawXSSknnGB0P3m98WLzRP4n/z+Nw5q3SCC xX2TOgP2MYEG14YJ2XJ9qDC/lJvclfjS+osRrC1A71E/wf7jN8c= =+4eA -----END PGP SIGNATURE----- --=-fJp7rziJk7MJM4rnRMhh--
