Hi, Looking at brcmfmac in Linux 3.16 with a BCM43241 SDIO card, I noticed that brcmf_construct_reginfo() constructs and submits a really large (1.5kb) request to the card. However, the actual request seems really small and trivial (a header, the word "chanspecs" and not much more), and we end up sending a whole lot of zeroes to fill the 1.5kb allocation (MEDLEN). I can understand that the card may wish to send 1.5kb in response, but does the request itself really need to be the same size?
The main reason is indeed that the request buffer is used by the device firmware for the response message. That is a design decision in the firmware that we must adhere to.
