Subject: [PATCH] brcmfmac: coarse support for PCIe shared structure rev7
|
|
|
|
Revision 7 of PCIe dongle interface increases the item size of tx and rx
|
|
complete rings to accommodate extra payload for new feature. This patch
|
|
simply bump up the size of these two rings without adding the support
|
|
for utilizing the new space. This makes brcmfmac compatible with rev7
|
|
firmware.
