Before this change the throughput +was capped to 30 Mbit/s on Tegra, now throughput is at 40 Mbit/s, which is +a maximum throughput for the BCM4329 chip. The F2 block size is borrowed +from the downstream BCMDHD driver. The comment in the BCMDHD driver says +that 128B improves throughput and turns out that it works for the brcmfmac +as well. + +Signed-off-by: Dmitry Osipenko <digetx@gmail.com> +--- + drivers/net/wireless/broadcom/brcm80211/brcmfmac/bcmsdh.c | 4 ++++ + 1 file changed, 4 insertions(+) + +diff --git a/drivers/net/wireless/broadcom/brcm80211/brcmfmac/bcmsdh.c b/drivers/net/wireless/broadcom/brcm80211/brcmfmac/bcmsdh.c +index 0dc4de2fa9f6..318bd00bf94f 100644 +--- a/drivers/net/wireless/broadcom/brcm80211/brcmfmac/bcmsdh.c ++++ b/drivers/net/wireless/broadcom/brcm80211/brcmfmac/bcmsdh.c +@@ -45,6 +45,7 @@ + #define SDIO_FUNC2_BLOCKSIZE 512 + #define SDIO_4373_FUNC2_BLOCKSIZE 256 + #define SDIO_435X_FUNC2_BLOCKSIZE 256 ++#define SDIO_4329_FUNC2_BLOCKSIZE 128 + /* Maximum milliseconds to wait for F2 to come up */ + #define SDIO_WAIT_F2RDY 3000 + +@@ -920,6 +921,9 @@ int brcmf_sdiod_probe(struct brcmf_sdio_dev *sdiodev) + case SDIO_DEVICE_ID_BROADCOM_4356: + f2_blksz = SDIO_435X_FUNC2_BLOCKSIZE; + break; ++ case SDIO_DEVICE_ID_BROADCOM_4329: ++ f2_blksz = SDIO_4329_FUNC2_BLOCKSIZE; ++ break; + default: + break; + } |
