[PATCH net-next 0/2] cxgb4: reduce memory footprint for collecting firmware dump

Firmware dump can be large (upto 2 GB).  In low memory conditions,
ethtool fails to allocate such large memory.  So, use zlib deflate
to compress collected firmware dump.

Patch 1 updates collection logic to use compression.

Patch 2 adds zlib deflate to compress collected firmware dump.

Thanks,
Rahul
