module: nxos_rpm

- cisco.nxos.nxos
short_description: Install patch or feature rpms on Cisco NX-OS devices.
description:
- Install software maintenance upgrade (smu) RPMS and 3rd party RPMS on Cisco NX-OS
  devices.
version_added: 1.0.0
author: Sai Chintalapudi (@saichint)
notes:
- Tested against NXOSv 7.0(3)I2(5), 7.0(3)I4(6), 7.0(3)I5(3), 7.0(3)I6(1), 7.0(3)I7(3)
- Unsupported for Cisco MDS
- For patches, the minimum platform version needed is 7.0(3)I2(5)
- For feature rpms, the minimum platform version needed is 7.0(3)I6(1)
- The module manages the entire RPM lifecycle (Add, activate, commit, deactivate,
  remove)
- For reload patches, this module is NOT idempotent until the patch is committed.
