From 37cf4d1a9b0903b874a638d0f8649873ddde8a12 Mon Sep 17 00:00:00 2001 From: Shmulik Ravid Date: Tue, 5 Jul 2011 06:16:22 +0000 Subject: dcbnl: Aggregated CEE GET operation The following couple of patches add dcbnl an unsolicited notification of the the DCB configuration for the CEE flavor of the DCBX protocol. This is useful when the user-mode DCB client is not responsible for conducting and resolving the DCBX negotiation (either because the DCBX stack is embedded in the HW or the negotiation is handled by another agent in the host), but still needs to get the negotiated parameters. This functionality already exists for the IEEE flavor of the DCBX protocol and these patches add it to the older CEE flavor. The first patch extends the CEE attribute GET operation to include not only the peer information, but also all the pertinent local configuration (negotiated parameters). The second patch adds and export a CEE specific notification routine. Signed-off-by: Shmulik Ravid Signed-off-by: David S.
