> This patchset adds support for logging MCDI (Management-Controller-to- > Driver Interface) interactions between the sfc driver and a bound device, > to aid in debugging. > Solarflare has a tool to decode the resulting traces and will look to > open-source this if there is any external interest, but the protocol is > already detailed in drivers/net/ethernet/sfc/mcdi_pcol.h. > The logging buffer we allocate per MCDI context is a work area for > constructing each individual message before logging it with netif_info. > The reason the buffer is long-lived is simply to avoid the overhead of > allocating and freeing it every MCDI call, since MCDIs are already known > to be serialised for other reasons. > > -- > v3: add some explanations to cover letter and patch #4 > v2: avoid long lines in cover letter; fix multiline comment style Patch #4 doesn't apply cleanly to net-next, please respin.
