[ As I am trying to remove direct SKB list pointer accesses I am
committing this to net-next. If this causes a lot of grief I
can and will revert, just let me know. ]

I just have bcm4339 in hands, test the patch on i.MX7D sdb board with
bcm4339, it works fine with iperf testing.

Thanks, Andy
Can you do one more check? Please insert brcmfmac with module parameter
debug=2 and let me know if the following log message is seen:
brcmfmac: brcmf_sdiod_sgtable_alloc: nents=X
If not seen, the driver does not go through the patched code.
My kernel don't enable debug and DEBUG and CONFIG_BRCM_TRACING, I add the debug info in the brcmf_sdiod_sgtable_alloc(), and the log show the driver go through the sg path:
Log: brcmf_sdiod_sgtable_alloc: max_segs:128, sg_support:1, nents=35
Thanks, Andy
Works for me ;-)

Arend
