Subject: [PATCH net 0/2] bnxt_en: Fix MAX_SKB_FRAGS > 30

The driver was written with the assumption that MAX_SKB_FRAGS could
not exceed what the NIC can support.  About 2 years ago,
CONFIG_MAX_SKB_FRAGS was added.  The value can exceed what the NIC
can support and it may cause TX timeout.  These 2 patches will fix
the issue.

Michael Chan (2):
  bnxt_en: Mask the bd_cnt field in the TX BD properly
  bnxt_en: Linearize TX SKB if the fragments exceed the max
