Hi Dave
The subject for this should be "driver/net: enic: Try DMA 64 first, then
failover to DMA 32"
The "32" got truncated, please add this while committing. Let me know if
you want me to send another patch.
thanks

In servers with more than 1.1 TB of RAM, the existing 40/32 bit DMA
could cause failure as the DMA-able address could go outside the range
addressable using 40/32 bits.
The following patch first tried 64 bit DMA if possible, failover to 32
bit.
