[ Upstream commit 4635fd3a9d77581498f34ab9a7e4bcc211bf0a4c ]
Remove from supported_coalesce_params ETHTOOL_COALESCE_MAX_FRAMES and ETHTOOL_COALESCE_MAX_FRAMES_IRQ. As tx-frames-irq allowed user to change budget for iavf_clean_tx_irq, remove work_limit and use define for budget.
Without this patch there would be possibility to change rx/tx-frames and rx/tx-frames-irq, which for rx/tx-frames did nothing, while for rx/tx-frames-irq it changed rx/tx-frames and only changed budget for cleaning NAPI poll.
