tipc: rename struct media to struct tipc_media

2011-12-30T02:53:29Z

Give it a meaningful prefix, as suggested by DaveM, so that it is consistent with things like struct tipc_bearer, and so it isn't confused with anything else. This has no impact on the actual runtime code behaviour. Signed-off-by: Paul Gortmaker

tipc: Eliminate useless memset operations in Ethernet media support

2011-12-27T16:33:44Z

Gets rid of two pointless operations that zero out the array used to record information about TIPC's Ethernet bearers. There is no need to initialize the array on start up since it is a global variable that is already zero'd out, and there is no need to zero it out on exit because the array is never referenced again.

tipc: Do timely cleanup of disabled Ethernet bearer resources

2011-12-27T16:33:42Z

Modifies Ethernet bearer disable logic to break the association between the bearer and its device driver at the time the bearer is disabled, rather than when the TIPC module is unloaded. This allows the array entry used by the disabled bearer to be re-used if the same bearer (or a different one) is subsequently enabled. Signed-off-by: Allan Stephens Signed-off-by: Paul Gortmaker

tipc: Minor optimization to deactivation of Ethernet media suppot

2011-12-27T16:33:41Z

Change TIPC's shutdown code to deactivate generic networking support before terminating Ethernet media support. The deactivation of generic networking support causes all existing bearers to be destroyed, meaning the Ethernet media termination routine no longer has to bother marking them as unavailable.

tipc: Hide media-specific addressing details from generic bearer code

2011-12-27T16:33:36Z

Reworks TIPC's media address data structure and associated processing routines to transfer all media-specific details of address conversion to the associated TIPC media adaptation code. TIPC's generic bearer code now only needs to know which media type an address is associated with and whether or not it is a broadcast address, and totally ignores the "value" field that contains the actual media-specific addressing info. These changes eliminate the need for a number of endianness conversion operations and will make it easier for TIPC to support new media types in the future.

tipc: Add new address conversion routines for Ethernet media

2011-12-27T16:33:27Z

Enhances TIPC's Ethernet media support to provide 3 new address conversion routines, which allow TIPC to interpret an address that is in string form and to convert an address to and from the 20 byte format used in TIPC's neighbor discovery messages. These routines are pre-requisites to a follow on commit that hides all media-specific addressing details from TIPC's generic bearer code. Signed-off-by: Allan Stephens Signed-off-by: Paul Gortmaker

tipc: Improve handling of media address printing errors

2011-12-27T16:13:06Z

Enhances conversion of a media address to printable form so that an unconvertable address will be displayed as a string of hex digits, rather than not being displayed at all. (Also removes a pointless check for the existence of the media-specific address conversion routine, since the routine is not optional.) Signed-off-by: Allan Stephens Signed-off-by: Paul Gortmaker

tipc: Register new media using pre-compiled structure

2011-12-27T16:13:05Z

Speeds up the registration of TIPC media types by passing in a structure containing the required information, rather than by passing in the various fields describing the media type individually. Signed-off-by: Allan Stephens Signed-off-by: Paul Gortmaker

tipc: Lower limits for number of bearers and media types

2011-09-18T02:55:07Z

Reduces the number of bearers a node can support to 2, which can use identical or non-identical media. This change won't impact users, since they are currently limited to a maximum of 2 Ethernet bearers, and will save memory by eliminating a number of unused entries in TIPC's media and bearer arrays.

tipc: Remove redundant search when enabling bearer

2011-09-18T02:55:06Z

Removes obsolete code that searches for an Ethernet bearer structure entry to use for a newly enabled bearer, since this search is now performed at the start of the enabling algorithm. Signed-off-by: Allan Stephens Signed-off-by: Paul Gortmaker
