The rx_nents and tx_nents are redundant. rx_buf and tx_buf can
be used for total number of SG entries.

 This is correct. Just a nit, may be rx/tx_buf can be changed to
 rx/tx_count to make it more clear.


 Yes, rx/tx_count will be more meaningful. rx/tx_buf gives the
 impression that it is uchar buffer.  I will change that.

 Thanks,
 Abhishek
