Subject: [PATCH net-next 0/2] bnxt_en: Increase maximum RX ring size when jumbo ring is unused

The RX jumbo ring is automatically enabled when HW GRO/LRO is enabled or
when the MTU exceeds the page size.  The RX jumbo ring provides a lot
more RX buffer space when it is in use.  When the RX jumbo ring is not
in use, some users report that the current maximum of 2K buffers is
too limiting.  This patchset increases the maximum to 8K buffers when
the RX jumbo ring is not used.  The default RX ring size is unchanged
at 511.

Michael Chan (2):
  bnxt_en: Don't use static arrays for completion ring pages.
  bnxt_en: Increase maximum RX ring size if jumbo ring is not used.
